Hello! I since kernel v3.1, my system suffers from lock-ups because of the rtl8192se driver. v3.0 is still fine.

I will try the recently proposed patch for another problem from Stanislaw, [PATCH v2] rtlwifi: fix lps_lock deadlock, to check if it resolves my issue as well. But I think that Mike might be affected by the change again...
From a quick look, Stanislaw's patch should fix your system. If not, then please consider pulling a git tree and checking out commit 34ddb20, which is the one before 67fc6052.
