I was able reproduced the issue with the current crypto-2.6 tree 180ce7e...
The issue does not show up with CONFIG_DEBUG_SLAB nor CONFIG_SLUB and
CONFIG_SLUB_DEBUG_ON. It seems the issues is really related to hmac.
Loading tcrypt with modes not using hmac seem to run fine. During my
tests the system freezes eventually when doing multiple modprobes of
tcrypt like this:
modprobe tcrypt mode=100
I get multiple OOPses with a subsequent panic looking like this:
