Hi! My problem started many weeks ago, with a cheap amd64 system running i386 dfly240 and after updating to something (I believe) between 2.5.1.750 and 850, and any later version. The system stopped suddenly responding to the keyboard and the mouse. As far as I remember, it only happened within X11, and maybe only while also using the network. For example restarting firefox with 10-20 open tabs often ended with a freeze.
The same hardware is now running x86_64 v2.6.3.2.gdda6b-RELEASE GENERIC+SMP and I just saw the same problem again. Sadly I am neither able to interact with the system after a freeze nor do I find any relevant information after restart, besides some hammer cleanup: HAMMER(ROOT) recovery check seqno=011afb3f HAMMER(ROOT) recovery range 3000000003147fb8-300000000314f498 HAMMER(ROOT) recovery nexto 300000000314f498 endseqno=011afbd9 HAMMER(ROOT) recovery undo 3000000003147fb8-300000000314f498 (29920 bytes)(RW) HAMMER(ROOT) Found REDO_SYNC 30000000030d4200 HAMMER(ROOT) recovery complete HAMMER(ROOT) recovery redo 3000000003147fb8-300000000314f498 (29920 bytes)(RW) HAMMER(ROOT) Find extended redo 30000000030d4200, 474552 extbytes HAMMER(ROOT) End redo recovery Any ideas, what I could do before or after it happens the next time, that might give my some info what's going on?
