Bug#438594: VFS: unable to mount root fs on unknown-block
Package: linux-image-2.6.18-5-486
Version: 2.6.18.dfsg.1-13etch1
Severity: critical
Justification: breaks the whole system
After installing the new linux-image package and rebooting, the boot process failed with:
RAMDISK: compressed image found at block 0
RAMDISK: incomplete write(-1 != 32768) 4134304
VFS: cannot open root device "/dev/hda2" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: unable to mount root fs or unknown-block(0,0)
I appended ramdisk=65536 to grub's root line, and that got rid of the RAMDISK errors, but the boot continues to fail with the same VFS error.
Linux-image-2.6.18-4-486 works fine.
