 Posted: Sat Mar 11, 2006 6:20 am Post subject: kernel panic (solved) |
 |
|
Sorry for the n00b question,but I've read the whole threads of the forums.
When i boot up the system,it showed
| Code: | VFS: cannot open root device "sda9" or unknown-block(0,0)
please append a correct "root= " boot option
kernel panic-not syncing :VFS unable to mount root fs on unkown-block(0,0) |
I've checked the GRUB ERROR COLLECTION and some other threads.As these threads mentioning,I compiled the my NVIDIA SATA chip support into kernel,and of course I did comment the filesystem option too.here's the excerpt of my kernel configuration.
| Code: | Device Drivers --->
SCSI device support --->
<*> SCSI device support
<*> SCSI disk support
<*> SCSI generic support
Device Drivers --->
SCSI device support --->
SCSI low-level drivers --->
[*] Serial ATA (SATA) support
< > ServerWorks Frodo / Apple K2 SATA support (EXPERIMENTAL)
< > Intel PIIX/ICH SATA support
<*> NVIDIA SATA support
< > Promise SATA TX2/TX4 support
< > Promise SATA SX4 support
< > Silicon Image SATA support
< > SiS 964/180 SATA support
< > VIA SATA support
< > VITESSE VSC-7174 SATA support |
And my grub.conf like this
| Code: | title=Gentoo Linux 2.6.15
root (hd0,7)
kernel /kernel-2.6.15 root=/dev/sda9
|
| Code: | PARTITION FS MOUNT PT.
--------------------------------
/dev/sda1 ntfs
/dev/sda5 ntfs
/dev/sda6 ntfs
/dev/sda7 ntfs
/dev/sda8 ext2 /boot
/dev/sda9 reiserfs /
/dev/sda10 reiserfs /home
/dev/sda11 swap none |
so what's wrong with it? My motherboard is ASUS K8N4-E. If you need more information,i'll post 'em as much as possible.
thanx in advance.

| Have you included reiserfs directly in the kernel? |

Hi.
From your descriptiion, I suspect that you forgot to copy the new kernel into /boot or that you forgot to mount /boot before copying the kernel.

yeah,definitely i did include reiserfs int the kernel.

I've copied bzImage from /usr/src/linux/arch/i386/boot directory to the /boot partition.and here's my grub.conf about the /boot
| Code: | | /dev/sda8 /boot ext2 auto,noatime 1 2 |

If you don't believe me, compare the dates in uname -v and ls -l /usr/src/linux/arch/i386/boot/bzImage.

I ran uname -v,here's the result
| Code: | | #1 SMP Tue Aug 2 16:32:16 UTC 2005 |
and here's the result of ls -l /usr/src/linux/arch/i386/boot/bzImage
| Code: | | #-rw-r--r-- 1 root root 2450285 Mar 11 21:51 /usr/src/linux/arch/i386/boot/bzImage |
Does that mean I didnt actually copy the new kernel into /boot?
But I've mounted /boot and ran the command
| Code: | #cd /usr/src/linux/
#cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.15 |

tried it,too.no luck.
it seems that the sata_nv modules doesnt load when boot up,so it couldnt recognize my SATA HD.
weird,i've compiled it into kernel.
i tried some other kernels,too.no luck,either.

| 1. The kernel has a size of 2,4MB. This is too big. |

what?  nForce 4 chipset doesnt support Maxtor SATA HDDs ? But it works well under my windows xp.

Yes, it does! If you notice, the kernel you're running is from August 2005 and the one you've built is from March 2006. You need to do the following to install your new kernel.
| Code: | # cd /usr/src/linux
# mount /boot
# cp arch/i386/boot/bzImage /boot/kernel-<version>-gentoo
# cp .config /boot/config-<version>-gentoo
# cp System.map /boot/System.map-<version>-gentoo |
Make sure you replace <version> with your kernel version. Then make sure that the kernel line in grub.conf includes the correct kernel name.

Still doesnt work. Actually I could see the other modules I've compiled into kernel loading while booting up except sata modules.But I've compiled 'em all into kernel,is it really the problem of Maxtor SATA HDDs?

I don't think it is cause of your sata harddrives cause I was using them for 1,5 years and I didn't have too much problem,except the install  . Try using livecd kernel to see what it does, the doc about using the livecd kernel is here http://www.gentoo.org/doc/en/gentoo-x86-tipsntricks.xml#doc_chap1 .

 still the same result.
everything loaded except the sata modules.
forgot to mention that my system was built by GCC 4.1,glibc 2.4. Is that the problem?

Well, it might be. Then again, it might be something else.
Is udev working? Did you emerged and added to the init scripts hotplug and coldplug? Look at rc-update show | grep -e coldplug -e hotplug. When you boot with the live-cd, check that you have the device node for sda9 under /mnt/getnoo/dev.

yeah,i've emerged udev.and here's the result of rc-update show | grep -e coldplug -e hotplug
| Code: | cold plug || default
hot plug || default |
so it's not the problem,too.
My installation is followed Nesl247's The Evolution Mission Install Guide 1.0.2,and my cpu is sempron 64bit 3000+.So i edited the make.conf like this (i didnt use 64bit installation)
| Code: | # Evolution Mission's default make.conf - gcc4.1
CFLAGS="-O2 -march=k8 -pipe -ftracer -fweb -frename-registers -fforce-addr"
CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden"
#LDFLAGS="-Wl,-O1 -Wl,--sort-common -Wl,-Bdirect -Wl,-hashvals -Wl,-zdynsort"
CHOST="i686-pc-linux-gnu"
ACCEPT_KEYWORDS="~x86"
PORT_LOGDIR=/var/log/portage
PORTDIR_OVERLAY="/usr/local/portage /usr/local/overlays/gnome-experimental"
PORTDIR_OVERLAY="${PORTDIR_OVERLAY} /usr/local/overlays/emission-guide"
PORTAGE_NICENESS=10
PORTAGE_ELOG_CLASSES="warn error log info"
PORTAGE_ELOG_SYSTEM="save"
FEATURES="ccache distlocks -userpriv parallel-fetch confcache"
USE="nptl nptlonly glibc-omitfp"
CCACHE_SIZE="2G"
CCACHE_DIR="/var/tmp/ccache"
INPUT_DEVICES="keyboard mouse evdev"
#VIDEO_CARDS=""
|
So will the option k8 be the trouble ? Most users of the Evolution Mission Installation didnt get wrong.

Well, until a few days ago, I would have said the problem was the -march=k8 with a 32bits install. However, I've been told that works. From your comment, I have another report that it works.
I wonder whether if you could have problems with the CFLAGS, FEATURES and USE flags. Can you confirm that the users of that method use the same and that their systems run without problems? I'm not convinced that your problem is caused by these - the kernel doesn't crash, it just has a problem with the sata_nv driver. Have you tried creating a kernel with genkernel? Does it work? I prefer hand built kernels, but that would help determine if the problem is in the kernel.

genkernel,unable to work,either. here's the error log
| Code: | RAMDISK:Couldn't find vaild RAM disk image starting at 0
UDF-fs:No partition found (1)
XFS:bad magic number
XFS:SB vaildate failed
kernel panic -- not syncing:VFS:unknown-block(1,0) |
and i dont think CFLAGS, FEATURES and USE flags would be the problem,cuz it's the dafault setting in Evolution Mission Installation,I didnt modify anything.
and one thing more should be mentioned,my kernel froze just before the some CPU Frequency scaling modules which's used for AMD Cool n' Quite loading.here's the kernel config which's for AMD Cool n' Quite.Does that matter?
| Code: | Power management options ---> (Kernel options for Cool'n'Quiet/Powernow)
[*] Power Management support
CPU Frequency scaling --->
[*] CPU Frequency scaling
< > /proc/cpufreq interface (deprecated)
Default CPUFreq governor (performance) --->
<*> 'powersave' governor
<*> 'userspace' governor for userspace frequency scaling
[ ] /proc/sys/cpu/ interface (2.4. / OLD)
<*> CPU frequency table helpers
<*> AMD Opteron/Athlon64 PowerNow! |

About the genkernel problem, did you remember to add the initrd line to grub.conf? With genkernel, you need to use an initrd image.
I don't know if the AMD Cool n Quiet only works in 64bits mode or not. You also say that you have a Sempron, I don't know if that only works with AMD64 and Opteron chips or if it also works with Sempron chips.

a Sempron is a tuned down Athlon 64 so it should work

I guess I forgot the initrd image.So I re-emerge genkernel again,and use genkernel all to compile it,but somthing wrong happened.
