You're right, Suyayu - the bug that's being worked on is the plymouth
bug (well actually, I think it's a kernel bug, but it displays plymouth
so plymouth is the visible part.) But that won't fix the core problem -
the kernel panic - because we don't yet know what's causing Alex's
system to panic in the first place.

I think kernel panics are usually because of hardware issues, device
driver issues, or a genuine kernel bug (but I think the latter is by far
more rare.) Do you have any hardware that might be suspect, Alex? Maybe
a RAM module you recently swapped into the machine? 

One tool that might be useful is called kdump. It's part of Fedora and
it loads a second uncrashed kernel to capture data from the crashed
kernel to help figure out what's going on. There's some instructions on
how to use kdump in the Fedora wiki:

I would imagine if the output of running kdump after triggering a crash
doesn't indicate the problem in an obvious way (e.g., might be
obvious-ish if there was mention of the brand name of a piece of hw
you're aware of in the output), I think the output would certainly make
for a good bug report.

Hope this helps,
