[Madwifi-devel] kernel messages with r2405 + crash

[Derek S. <de...@in...>]

Hi,
 running release r2405 on a X86 transmeta processor,
(adhoc, g rates), 
I get these kernel messags every couple of minutes.


BUG: warning at kernel/softirq.c:141/local_bh_enable()

On this transmeta box kernel messages are sent to the serial port. A 
monitoring box is used to capture and record all messages.
If you do
dd if=/dev/zero of=/dev/kmem 
there are messages about panic and copy proesses.


And then at some times of the day, the transmeta running r2405 crashes. No 
kernel messages. No serial messages. The processor seems to lock up the 
hardware. Does the hal lock the pci bus? In comparison, a similar box, but 
running much earlier versions of the svn does not crash.
