If you find your system isn’t booting sometimes and you get this funny error message, edit your kernel boot line in /boot/grub/menu.lst:
kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=75a92494-bdae-4715-92d9-f06d1887008e ro all_generic_ide
e.g – Add the all_generic_ide parameter. All should be fine once again. I believe this is a strange Ubuntu kernel bug, although I’m not sure.

initrd /boot/initrd.img-2.6.24-16-generic
quiet
But didnt work form.
You sugestion works fine
There’s a host of bug reports on failing to boot (e.g.
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/106063) but they seem to concern only linux 2.6.20.
I’ve noticed this error (with subsequent “read error on device…” and “Buffer I/O error on device”) popping up after the computer has been in use for some time, and the disk completely locking up after that – not even responding to smartctl.
This is with current kernels, and I notice you use 2.6.24, so I’ll try your suggestion. Do you have any pointers to any further information on what this is about?
