[issue1033] HAMMER: fatal trap 12 when mount_hammer

[Antonio Huete Jimenez <sinknull@xxxxxxxxxxxxxxxxxxxxxxx>]

New submission from Antonio Huete Jimenez <tuxillo@quantumachine.net>:

As a lot of times before, I've loaded my vinum configuration and tried to mount
my hammer volume (/dev/vinum/datapool) with a surprise.

mount_hammer drops the kernel to a fatal trap 12. For details take a look to
images on leaf. This is reproduced everytime I try to mount that HAMMER volume.

I don't really know if there's something corrupt in my HAMMER volume. 

Looking to that p output we see that:
master# addr2line -e /kernel c046de8c
/usr/src/sys/libkern/crc32.c:116

And that line corresponds to:
        while (size--)
                crc = crc32_tab[(crc ^ *p++) & 0xFF] ^ (crc >> 8);

I'm afraid I can't specify exactly the HAMMER version that this kernel is using,
but it must be that "HAMMER 54/Many: Performance tuning" or so.

If you need further information, let me know and I'll try to provide it.
