two (SATA related?) panics on yesterday's CURRENT

  I have installed CURRENT on a brand new SuperMicro 5013C-M.
Motherboard is SuperMicro P4SCi:
http://www.supermicro.com/products/motherboard/P4/E7210/P4SCi.cfm

A single SATA drive is Seagate Barracuda(?):
ad0: 76319MB <ST380013AS/3.18> [155061/16/63] at ata0-master SATA150

The first panic is:
kdb_enter(c062e3f8,c067bec0,c0640a01,d3fb8bf0,100) at kdb_enter+0x30
panic(c0640a01,c19244a4,c0c44c60,c062968e,c155c160) at panic+0xce

fork_trampoline() at fork_trampoline+0x8

After that I can't fsck and remount drive, because of second panic
(not ATA related):

I have crashdump only of second panic.

P.S. 5.2.1-RELEASE works ok on it.
