Public bug reported:
I use this laptop for scientific analysis, so the performance loss is
very noticeable. This happened suddenly, and does not appear to be
related to a cooling problem. Obvious things like rebooting or manually
setting the CPU governor to 'performance' don't resolve this.

This problem is only reproducable while using init=/sbin/e4rat-preload.

kernel panic when updating

I was just able to reproduce the problem by using e4rat instead of
ureadahead, and installing updates which included libc6.
:$cat /proc/cmdline

No, this problem did not occur before I upgraded to Saucy.

Title:
kernel panic when updating
Status in “linux” package in Ubuntu:
I cannot install any new software, since dpkg got interrupted mid-
upgrade and calling 'dpkg --configure -a' triggers the kernel panic.
I've been trying to reproduce the panic on a fresh install of the daily
build on an external drive, but so far without success.

It looks like the panic only occurs when updating libc6. I found this
out because usually after the panic, I run 'sudo dpkg --configure -a'
and I can continue the update, but since the last panic dpkg starts by
configuring libc6, and then the panic occurs again. So at this point,
the panic is 100%
Looks like a correction is in order, I just had a kernel panic while
running the mainline kernel. While the problem always occurs while
updating, it does not occur on every update, so it's hard to reproduce.
I've typed over the exact error messages I get on screen when it
happens:

Public bug reported:
Every time I update ubuntu 13.10 using sudo aptitude update && sudo
aptitude safe-upgrade, my pc freezes with a kernel panic: trying to kill
init. The error code is ff00. So far this has happened 4 or 5 times,
always when installing updates.
