[Bug 445852] Re: SSD stall during boot

#75 is correct. My karmic install always gives the error (even with
2.6.29-rc3*). But my jaunty never gives the error, even with 2.6.31-16.
However, there is one more difference between my karmic and jaunty
installs: karmic uses ext4, while jaunty uses ext2 (and for the record
all of those are inside LVM).

Could it be something related to ext4? I notice that the bug triggers
during or right after filesystem check/mount (mountall). But I have not
been able to reproduce this bug by doing filesystem checks/mounting of
the karmic-ext4 partition under jaunty.

I have not been able to debug it further. Debugging upstart to see
exactly when the bug triggers generates way too much output.

I tried disabling ureadahead, but that didn't make any difference.

*Note that the error message changed between 2.6.29-6 and 2.6.30-rc1,
but it still triggers an error message and the same delay.
