Ralink RT2501/RT2573 USB Wireless Adapter crashes kernel 2.6.37

Ralink RT2501/RT2573 USB Wireless Adapter crashes kernel 2.6.37

[Eric Fernandez]

Hi,

I reported this issue for two Linux distribution (Arch and Mandriva)
after upgrading to kernel 2.6.37 and is rather critical for users of
RT2573 Ralink USB Wireless adapters. This leads to complete system
crash, which is solved either by using a wired ethernet connection, or
by downgrading the kernel to 2.6.36 version. This happens in
particular when watching a streaming video (e.g. Youtube). I do not
see any entry in the log files. The sound goes to a loop, system is
completely blocked and only a hard reset will allow rebooting.

I feel this issue has been reported for other distributions too:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/673682
and this may be related:
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-January/002935.html

I tried to use the compat-wireless drivers (2011-01-30), which were
compiled correctly, but rt2x00 module loading segfaults when inserting
the USB adapter.

What can I do to help squashing this issue?

Many thanks in advance.
Eric

I have no immediate idea about the cause of the crash, but
did you make sure you unloaded _all_ wireless modules
before plugging in the USB adapter after installing
compat-wireless?  "make unload" or a reboot should do the trick.

If it still crashes, can you check dmesg for the crash messages?


Thanks,
Johannes

Hi Johannes,

This happend on reboot, yes. I rebooted without the adapter plugged
in, then I left udev load the modules upon plugging the USB adapter.
I'll send you the error message in a few hours when I am back home.
Note that when the system freezes (the original bug, with the modules
from kernel 2.6.37), I get no log messages whatsoever.

Thanks,
Eric

this is what I get in /var/log/messages after I plug in the adapter:

Can you double check rfkill module is from compat-wireless
and not from you kernel?
Or maybe compat-wireless is currently broken, try an older tarball.
It doesn't look at first glance like a rt2x00 specific issue.

BTW, output from dmesg also contains the actual crash
reason which is not in /var/log/messages due to your syslog config.


HTH,
Johannes

Hi John,

Unfortunately I have not got another machine. I'll see what I can do.

What Leonardo is reporting might be the same manifestation of the same
issue. This crash does not happen with kernel 2.6.36, and with 2.6.37,
it happens quite rarely. However, I can increase the chances of it
happening by heavily browsing the Internet, and especially when
seekinbg in Youtube videos, leading to a lot of downloading.

Another post in this mailing list is this one:
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-January/002935.html
since it reports a crash issue specific to 2.6.37 that did not happen
in 2.6.36 (started with
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2010-December/002868.html).

Finally, this issue seems to affect other users:
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."

Can you use netconsole over the wired link to capture a backtrace
when the lock-up occurs?

Ralink RT2501/RT2573 USB Wireless Adapter crashes kernel 2.6.37

[Eric Fernandez]

Hi,

This follows the issue I reported two days ago. I have had two crashes
tonight using kernel 2.6.37-5 on Archlinux 64. Unfortunately, this
leads to no log in the kernel log whatsoever. The machine freezes
completely, if sound is played it loops. I cannot confirm if I can ssh
to the box (have only one computer), however, this is linked to the
usage of my wireless adapter, since switching to wired ethernet does
not lead to this issue.
One thing: when I reboot (hard reset), I need to unplug my adapter so
that it works after login. Otherwise, it seems to associate fine with
the router, but strangely I cannot download anything. Using gkrellm, I
can see that it sends some packets to the router at regular interval,
but does not download. I don't know if this is significant and if this
can help identify the issue.

I would be very keen to help, but without log messages I am stuck. Any
suggestions?

Thanks in advance.
Eric
