Hummm,
should I consider this geek humor or are you serious, the CPU is rather
slow (imho)?
Anyway, tweaking the iterationcount didn't chaneg a thing, messing with
the params did not help either.
The Backtrace does not really help a lot, I guess:
(gdb) bt
#0 0x000000000040d3fe in sigvtalarm ()
#1 0x0f0000000fc0c748 in ?? ()
#2 0x0000000000000000 in ?? ()
Well at least we know the crash happens in sigvtalarm, which I assume is
a signal handler of some sort within cryptsetup.
Regards
-Sven
