I'm getting regular crash reports for which I'm having trouble figuring
out what's going on exactly. Those are with my tree or bk 2_4_devel, but
the problem may be present elsewhere.
So basically, the kernel tends to die in various locations where things
should be just fine, but I did notice one thing: In most of these cases,
I had softirq around in the backtrace (either running in softirqs, or
having do_softirq() in the backtrace). There is one case where I didn't
have it: it dies inside power_save(), so probably because an interrupt
that happened just before messed things up.
I'm wondering if we might be running into some stack overflow...
Any clue ?

I don't really know, but I can confirm that both 2.2.x and 2.4.x kernels
are unstable on a beige g3 and a bmac equipped b/w g3. I can crash them
rather easily with regular programs, given a day or two. I have not seen
similar instability on other machines (dual g4, 7600, all nubus).
Unfortunately, I don't have any time to track it down right now :(

I've been able to trace that to the mace and bmac ethernet drivers, which
are *very* unreliable in 2.2. Get the latest drivers from Donald Becker for
tulip, rtl8139, eepro100, etc. and you're set. I haven't tried 2.4 yet.
