Bug Description

With the latest 2.6.30-10-generic kernel on my Lenovo X200 laptop (running a 64-bit OS), the boot drops into the initramfs shell saying it can't find the root device; however just hitting ctrl-D and continuing works fine and the system boots up as normal. It seems that the 2.6.30-10 kernel reaches initramfs almost instantly, without enough time for the ahci driver to find the internal HD in my laptop, and the sleep waiting for the root device is also very short. Should be an easy fix in the initramfs I guess.

I just noticed a string of lines like:

sleep: invalid number '0.1'

in the console before the message about not finding the root device. So I guess something changed the version of sleep in the initramfs from klibc to busybox, since:

/usr/lib/klibc/bin/sleep 0.1

works fine, but

/usr/lib/initramfs-tools/bin/busybox sleep 0.1
sleep: invalid number '0.1'

so I guess this is not a kernel bug, but rather an initramfs-tools bug.

affects:

linux (Ubuntu) → initramfs-tools (Ubuntu)

Thanks. This is also bug 391299, for which I've just uploaded a fix. Note that you'll need to run 'sudo update-initramfs -u' by hand after upgrading busybox-initramfs, due to a quirk of the dependency layout.
