I have reported this issue on the linux-wireless list, but was advised
to post on that list specifically.
I use an Edimax EW-7318USG adapter that uses the rt73usb module. My
distro is Archlinux 64 on Gigabyte ga-p55m-ud2 with i7 860 processor.
I use the proprietary nvidia driver.
After the kernel has been upgraded to kernel 2.6.37, I noticed random
crashes which I did not have with kernel 2.6.36. The system freezes
entirely, and sound loops for a few seconds. Only a hard reboot works.
On restart, I do not see any message in the kernel log whatsoever,
which makes the problem difficult to diagnose. Often, I need to unplug
my wireless adapter to make it work again (gkrellm shos that it is
trying to send packets to the router, but never downloads anything).
However, the problem entirely disappears if I downgrade to kernel
2.6.36, or if I use a wired Ethernet conection instead of wireless
with kernel 2.6.37. Furthermore, this happens especially when doing
heavy browsing (many tabs in Firefox) or watching videos on Youtube,
and seeking within the video.
I found out or was told that crashing issues specific to rt73usb with
kernel 2.6.37 has been reported in various ways:
since it reports a crash issue specific to 2.6.37 that did not happen
in 2.6.36 (started with
What Leonardo is reporting might be the same manifestation of the same issue.
3) This issue seems to affect other users from other distributions:
http://ubuntuforums.org/showthread.php?t=1613049&page=2 "There is a
fairly easy to trigger crash in this one with my USB Ralink
Technology, Corp. RT2501/RT2573 Wireless Adapter (rt73/rt2x00lib). I
am trying to get a proper snapshot of the trace for a report but at
least people might want to be a bit careful."
I would be very keen to help squashing this issue, unfortunately as I
wrote, I do not get any messages in the log when that happens. I
cannot confirm if I can ssh to the computer, as I only have one.
Is there a way to increase the verbosity of crash messages, hoping to
capture what happens when the system is freezing ?
I hope this helps.
