New description:
Several times a day, the Atheros card stops working and ksoftirqd_CPU0
starts using all CPU. Traffic doesn't seem to affect this (much).
The PC doesn't crash, though, and the problem can be resolved by doing
{{{ifdown ath0 && sleep 10 && ifup ath0}}}. It hangs sooner if I remove
the delay.
There is nothing in syslog.
The only parameters set are: mode AP, essid, restricted wep key and
channel (2.4GHz) and the interface is added to a bridge.
Kernel is version 2.4.25 with MOSIX, hostap, ppscsi and ITE8212 patches.
Distribution Debian 3.1. Machine is Pentium PRO. Card vendor is Well.
Driver versions below.
There are also 2 3com NICs and an ITE IDE controller on the PCI bus and
another 3com, a sound card and a video card on ISA, but I've double-
checked the machine for any conflicts.
The radio environment is rather noisy.
Perhaps I should mention that the PCI bus is ver 2.1 and I'm using a
computer quality DC-DC converter to supply 3.3V to the card. But even if
it's a non-standard setup, I think that the driver should either
honourably crash or catch and fix the error.
Thanks in advance for a resolution and I'll be glad to help debug the
problem.

Comment:
Try if trunk solves the issue. If not, you could try to remove the other
cards one by one, to see whether there is some (unspotted) conflict. In
addition, you should try the steps used in the if{up,down} configuration
manually to see which of them actually causes the issue.
