Red Hat Bugzilla – Bug 425777
Laptop hangs when wireless association lost
Last modified: 2008-01-08 18:42:43 EST
Description of problem:
Over the past few weeks I have found that when association is lost to my home
wireless network (often caused by our answering machine interfering with the
router), the laptop is freezing and I have to do a hard reboot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Here's the laptop:
Can you capture the output of Alt-Sysrq-T?
I'll try, though it's usually in X when it happens and it doesn't react to the
keyboard at all.
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?
It isn't, no.
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
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.
