Hello here, i installed the system,compiled kernel with support for either PATA and SATA into the kernel (not Modules), so i did with drivers ofr my filesystems - ReiserFS and Ext3, but when i start booting into my new installation, it says
Mounting /dev for udev: [oops]
reason is like when mounting a filesystem and there is some wrong setting, like bas option, wrong fstype or bad superblock....or how was that message :)
...and it's fatal for booting so i cannot get over it. dmesg |tail doesn't give a clue, so i've no idea what's wrong. Here's my
lspci:
Code:

Hi,

the error message would be of great help here. Nevertheless there are a few things you can try.

  1. Make sure that your /etc/fstab is correct. Especially the root filesystem.
  2. Make sure you specified the correct root filesystem in your bootloader.
  3. Check if your root filesystem is writeable.
  4. Check again your kernel settings to make sure your filesystems are compiled in.


Btw. the link to your kernel config doesn't work: "The requested document was not found on this server."

Thx for reply, well,i hadn't more info,no useable error message or so, but i spotted new kernel sources (r9), so i compiled this new one (copied config from r8, maybe changed some settings,sadly i dunno which ones :-(), and got another error about udev: http://mrduck.hopto.org/tmp/101_4069.JPG ..it wasn't about fstab or menu.lst(in grub), but i had missing some important(like basic) thingy in kernel (again,don't remember what exactly it was :/ sorry) and got it working...will try to find back some info and post here, if anyone will experience this so he can find it helpful...:-) Thx

From the error message I would guess your kernel lacks DGRAM support so udev can't listen to the socket it requires.
DGRAM is a connectionless protocol (according to "man netstat") so I think it's either UDP or a UNIX protocol.
Please make sure that you have at least:
Code:

CONFIG_PACKET=m
CONFIG_UNIX=y
CONFIG_INET=y

as module or inkernel option set in your kernel config file.
