i had no visible ddb prompt unfortunately,
so no show registers, etc but i managed
a boot dump blindly.
(i did not have enough space at reboot
time, so i ran savecore manually later)
$ sudo savecore /var/crash
savecore: reboot after panic: pool_do_get: mcl2k free list modified: page
0xd7e2c000; item addr 0xd7e2c000; offset 0x0=0x754208 != 0xa39ee339
savecore: system went down at Thu Oct 23 18:08:04 2014
savecore: /var/crash/bounds: No such file or directory
savecore: writing core to /var/crash/bsd.0.core
savecore: writing kernel to /var/crash/bsd.0
it is not the first time i meet mr. pool_do_get,
but it is not something i can reproduce at will.
