My problem started many weeks ago, with a cheap amd64 system running
i386 dfly240 and after updating to something (I believe) between 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

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) 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?
