** Description changed:
PROBLEM
When a disk check is performed, the progress stalls somewhere around 70%
and will then take a very long time finishing the remaining percent (10
minutes or more).
TEST CASE:
(sudo aptitude install bootchart)
sudo touch /forcefsck && sudo reboot
POSSIBLE WORKAROUNDS
1. Removing "quiet" and "splash" from the kernel boot line
2. When the progress has stalled, switch away from the splash screen
using the left arrowkey (presumably any arrowkey works).
* Both these approaches speeds up the boot process to ~1 minute instead.
OBSERVATIONS
The fsck message "(...) non-contiguous (...)" Which I assume indicates
the end of the fsck, is printed in the Virtual Terminal ("outside"
plymouth) at around 70% + ~10-20 seconds.
Disk activity is null from this point on (presumed end of fsck above).
Bootchart crashes if trying to catch the whole boot at once with
plymouth (at least for my 1h boot).
This problem seems to occur in both plymouthd and mountall,
semi-simultaneously:
If you are in the plymouth screen, plymouthd is the cpu-gobbler, if you
switch away from it using the arrow keys, mountall instead takes over the
cpu-eating.

ORIGINAL REPORT
Binary package hint: mountall
On my system when fsck runs at boot plymouth % completion count goes up
quickly (<10 seconds) up to about 80% and then slows down considerably:
the complete fsck of my 125GB HD, 30% full takes more than 5 minutes.
While this goes on the text VTs are all completely blank: just a
blinking cursor.
An fsck from a recovery disk completes in ~10 seconds so it doesn't look
like "fsck just being slow".
This slowdown was *not* happening on 2010-04-14 with the PPA described
by this comment:
https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/554737/comments/25
The fix in the PPA is now in the mainline lucid but somewhere in between
then and today (2010-04-29) something introduced this slowdown.
