kernel 2 6 25 and udev 141 issue

18 Mar 2010

#the problem:

labsystem boot halts with this error:

Current udev only supports Linux kernel **2.6.25** and newer.
Your kernel is too old to work with this version of udev.


either upgrade kernel or downgrad udev, i downgraded udev

system setup before fix was applied:

usb boot stick: grml version: 2008.11 - Release Codename Schluchtenscheisser 2008-11-30

disk usage:
/dev/sda* not important

/dev/sdb1 boot,ext2
/dev/sdb2 lvm

/dev/sdc1 boot,ext2
/dev/sdc2 lvm

md0: /dev/sdb1 /dev/sdc1
md1: /dev/sdb2 /dev/sdc2

now the fix

i basically used [1] and [2] as reference. i don’t like that portage didn’t tell me that with a dependency issue.

  1. grml usb stick boot
  2. ‘Start mdadm-raid’ found in the bootlog on Console F1
  3. vgscan; vgchnage -ay (wait about 10-30secs)
  4. mount /dev/vg/root /mnt/root (create /mnt/root first)
  5. cd /mnt/root; chroot .
  6. emerge =sys-fs/udev/-146-r1 (did not work)
  7. emerge =sys-fs/udev/-141

    edit /etc/portage/package.mask

    # DON’T INSTALL udev > 141 without making a kernel update first (2010-03-18) sys-fs/udev-141

  8. exit; reboot

system setup after fix was applied:
