Seems be resolved in -rc2. Only in dmesg still I have messages "netlink: 140
bytes leftover after parsing attributes.". It seems be another issue.

Dmesg when CONFIG_LOCKDEP is set:

No, _SUPPORT means you could enable CONFIG_LOCKDEP, but we would like to
see this with CONFIG_LOCKDEP enabled.

Did you mean "CONFIG_LOCKDEP_SUPPORT"?
$ cat /boot/config-3.4.0-rc1 | grep CONFIG_LOCKDEP
CONFIG_LOCKDEP_SUPPORT=y

I'm not sure. Looks like there is deadlock or infinite loop in process
that holds rtnl lock. This can be wireless driver, wired driver or
generic network code bug.
Maciej, please recompile with CONFIG_LOCKDEP and check if it will not
find any deadlock. If not, when problem will happen please do
echo w > /proc/sysrq-trigger
dmesg -c > dmesg1.txt
echo t > /proc/sysrq-trigger
dmesg > dmesg2.txt
and provide those files.
Additionally there are also lot in dmesg:
netlink: 140 bytes leftover after parsing attributes.
This need to be investigated as well. Perhaps you could modify error
message, to show what netlink messages/attributes are processed.
Thanks
Stanislaw
