Bug#394200: kernel freezes (no panic), seems related to acpid

Correction: it happens regardless.

So to summarise everything so far:

There are two times when the kernel freezes:
  1. during the start of cupsd in rc2, after starting xdm, acpid,
     cpufreqd.
  2. at the end of rc0/6, when it says "restarting system". The
     scroll-lock/caps-lock leds briefly flash after "will now
     restart", then "restarting system" is printed, and it hangs.

I managed to get rid of (1) in a number of ways:
  a. start xdm at S99
  b. start acpid as a child of strace

(2) only happens when X has not been started.

So today I started experimenting with acpi=off and found that (1)
now also does not happen anymore, but that (2) does.

Then I removed acpi=off and found that (1) also does not happen
anymore. (2) still happens.

Fun.
