Can you capture the output of Alt-Sysrq-T?

Comment 2 Adam Huffman 2007-12-17 15:40:44 EST

I'll try, though it's usually in X when it happens and it doesn't react to the
keyboard at all.

Comment 3 John W. Linville 2007-12-19 09:21:44 EST

Someone has suggested that you might be using the ipw3945 driver rather than 
the iwl3945 driver ("ipw" vs "iwl").  I have no idea how they determined this 
from this bug report, but I thought I would ask...is that so?

Comment 4 Adam Huffman 2007-12-19 18:19:15 EST

It isn't, no.

Comment 5 John W. Linville 2008-01-04 17:30:10 EST

Could you add "options iwl3945 debug=0x43fff" to /etc/modprobe.conf, reboot, 
recreate the problem, then attach the contents of /var/log/messages to this 
bug?

Thanks!

Comment 6 Adam Huffman 2008-01-08 18:40:58 EST

I've added that setting but haven't seen the problem for a few weeks now, so I'm
closing the bug.  I'll re-open if it recurs.
