 Posted: Sat Mar 30, 2024 2:14 pm Post subject: Failing to boot after install |
 |
|
x86_64 system, installed with manual kernel config.
System gets to GRUB after powering on, then text flashes by and screen goes black, then two lights on the keyboard start flashing (caps lock and num lock I think), then system powers off.
I have installed an used gentoo several times in the past but install has changed a bit since then and I seem to have made some mistake. Where do I start troubleshooting? |

I followed this and my situation has improved. I how get enough of readout to see that booting fails due to kernel panic with one of the lines mentioning a problem with either UUID or PARTUUID, with makes me think I made a mistake with fstab. Is there is need to use UUID versus PARTUUID?
I will get these later today, along with my fstab.
Is there is sticky on using pastebin? I have used it in in the past but it has been a while. |

TCRT,
The kernel understands PARTUUID but not (filesyestem) UUID. That need the userspace mount command.
With no initrd, root=PARTUUID=... works but root=UUID=... breaks.
Its not /etc/fstab. That is on root and root is not yet mounted, so /etc/fstab cannot be read.
This explanation of the PC Boot Process may help.

TCRT,
you have as controller:
| Code: | 00:1f.2 RAID bus controller [0104]: Intel Corporation 82801 Mobile SATA Controller [RAID mode] [8086:282a] (rev 03)
Subsystem: Dell 82801 Mobile SATA Controller [RAID mode] [1028:0233]
Kernel driver in use: ahci |
but you are missing CONFIG_SATA_AHCI in your kernel .config. This is due you are also missing: CONFIG_SCSI
So, your kernel is not able to access the harddisk and gives you a kernel panic.
... maybe read more than only the chapter of the link I have given you ... also the starting article (and all linked articles from there):

That's fakeraid which should be avoided unless you need to dual boot Windows/Linux from the raid set.
Your HDD is a type of SCSI
| Code: | | # CONFIG_SCSI is not set |
so that munu mut be on as will as SCSI Disk support inside it.
Both must be <*>
# CONFIG_ATA is not set is another menu item. It contains all the low level ATA drivers (there are lots).
You need AHCI, as pietinger says.
At the moment, your kernel cannot see your HDD.

While we are poking about in your kernel.

This worked, I now have Gentoo installed and running. Thank you both very much.
pietinger, I saw a link you had posted to a youtube video explaining the kernel but haven't been able to find it again, do you have that link handy?
