Public bug reported:
Binary package hint: udev
Hi,
I have an IBM x3800 machine with the root disk connected to the on-board
aic94xx SAS controller. Sometimes, when I boot Gutsy or Hardy, I see
this from the kernel:
Loading, please wait...
[ 163.773690] input: AT Translated Set 2 keyboard as /class/input/input1
Begin: Loading essential drivers... ...

[ 224.087822] Capability LSM initialized
Done.
Begin: Running /scripts/init-premount ...
Done.
...after a minute or two I get dumped into an (initramfs) prompt. If I
rmmod aic94xx and modprobe aic94xx, the driver and firmware load
correctly. Further digging reveals that udev doesn't start until init-
premount, which means that there's nothing listening when the kernel
asks for the aic94xx firmware, which explains why the first attempt to
load aic94xx fails due to firmware load problems but the subsequent
attempt succeeds.
Solution: mv /usr/share/initramfs-tools/scripts/init-premount/udev to
/usr/share/initramfs-tools/scripts/init-top/udev and regenerate the
initramfs. I speculate that the qlaXXXX drivers might have the same
issue, though I don't have any hardware to test that theory.

udev needs to load before "Loading essential drivers" so firmware_helper will
work
