crash on sleep with 2.4.19-pre4-ben0

[Michel Lanners <mlan@cpu.lu>]

Hi all,

Recently I have a hard time sending my TiBook to sleep. It started
crashing often a few weeks ago, and now, with 2.4.19-pre4-ben0, it
crashes reliably all the time.

Here's what xmon tells me:

vector: 300 at pc=c001ef74 (T sys_capset + 0x8c), lr=c001ef58 (T
sys_capset + 0x70)
msr=1032, sp=c3fafdc0 [c3fafd10]
dar=496e7665, dsisr=42000000
current=c3fae000, pid=374, comm=pmud

Here's the code around pc and lr (in other words, forget the symbol info
from xmon):

c001ef38 <del_timer>:

c001efa4:       4e 80 00 20     blr

Per System.map, I was able to verify that at least one previous crash
(with 2.4.18-rc4-benh) was in the same place.

When these crashes started, I had changed, modulo kernel version of
course, these things:

- started to use unmasq_irq on the hd,
- installed pbbuttonsd & gtkpbbuttons

Removing both doesn't help. Also, it seems I need to power-off after a
crash to get airport back to life.

Anybody with more insight?

Thanks

Michel
