ok, ive got output from wine with "wine Steam.exe > steam.log 2>&1". This time magic-sysrq was working, so i was able to make a clean emergency shutdown (term,kill,flush2disk,unmount,reboot). Last line of the log is (left out "fixme" messages): > > > err:ntdll:RtlpWaitForCriticalSection section 0x14b7814 "?" wait timed out in thread 001f, blocked by 0020, retrying (60 sec) > err:ntdll:RtlpWaitForCriticalSection section 0x14b7814 "?" wait timed out in thread 001f, blocked by 0020, retrying (60 sec) > (... some fixme messages...) > err:ntdll:RtlpWaitForCriticalSection section 0x6899ea20 "x11drv_main.c: X11DRV_CritSection" wait timed out in thread 0024, blocked by 0009, retrying (60 sec) Google has some old results, but no solutions... i do not even think that this is the problem. Maybe its something with networking - local games with bots are working well.
