Sorry for the late notice; I haven't tried running new kernels on this
computer in a long time.
When I use 2.6.32 (or indeed 2.6.32-rc1), it works fine up until the
point where the wireless card is ifconfig'ed. Then not long afterward
(a few seconds to a minute) the system hangs.

While the system is hung, Alt-SysRq-keys still work but nothing else
shows up when I type (using a VT console, not X). However I don't know
what debugging to do or what to look for.
Under 2.6.31 everything works okay.
Any help appreciated,
Alan Stern

Did you test it with 2.6.32? Since 2.6.32-rc1 many fixes has been done
into kernel and would be nice if you could test against current
kernel.

The same thing happens with both 2.6.32-rc1 and 2.6.32. But not with
2.6.31.

Hmmm, that's odd. I haven't seen any other reports on this (on full system hangs that is).
It would be very hard to figure out what is going wrong without any form of logging of
an oops or something. Is there any way you can find out if any oops information is present?
What does Alt-SysRq-l tell us, what are the CPU's doing when the system is hung?

There is no oops. The system just stops responding to keystrokes other
than Alt-SysRq-*.

Unfortunately Alt-SysRq-l wasn't very helpful. The output is below
(captured using a serial console), starting from when I configured the
wireless interface. For thoroughness I have also attached the output
of Alt-SysRq-T in single-user mode, but it doesn't seem to contain
anything striking.
Could the problem be connected with CONFIG_4KSTACKS (which was enabled
in this kernel)?

Hmm, the stack overrun seems to be generated as part of the
Alt-SysRq-* handling, not of any rt61pci handling.
I noticed in the Alt-SysRq-T output that powersaving is enabled. We've
seen some strange behaviour on this, so could you disable that with:
iwconfig wlan0 power off
or run a kernel in which CONFIG_CFG80211_DEFAULT_PS is disabled.
Maybe that will fix the problem we are seeing?
Other than that I have no ideas on what is happening here.

It did indeed! Thank you very much. If you need a testbed to figure
out what's wrong with the power-saving code, just ask.

Great!
Thanks for testing and confirming.
I'll disable powersaving for rt2x00 for now.
And then to find the bugs in there before enabling it again :-(

It would be nice to have it in 2.6.32.y and 2.6.31.y when it is done.

Gertjan:
Sorry to bother you again, but I have run across a new bug affecting
my rt2561s card. It appeared in 2.6.33-rc1 and is still present in
-rc3. (This is with CONFIG_CFG80211_DEFAULT_PS disabled, not that it
should make any difference now.)
The card doesn't work. Although the firmware load appears to
succeed, "iwconfig wlan0" says no wireless extensions present.
The only clue I can offer is that "rmmod rt61pci" hangs in
wiphy_unregister() during the wait_event() loop near the start, because
rdev->opencount is equal to -1. This suggests a refcounting imbalance
of some sort.

Alan,

You need to set CONFIG_CFG80211_WEXT (it is default y).

Good point, that's a bug that will go away with CONFIG_CFG80211_WEXT,
I'll send a fix.

Many thanks. I'll test the patch and the config option tonight and
report back tomorrow.
