cinergyt2_query_rc() hangs. I'll try to look tomorrov, but I know nothing
about drivers/media/dvb/.
This log is strange, flush_work() should report every 30 seconds, but it
looks like wait_for_completion_timeout(HZ * 30) returns a lot earlier.
Could you also show the result of sysrq-T ?
Thanks!
Oleg.
