Description Alexander V. Chernikov 2009-04-27 23:40:01 UTC 
We've got several Intel S3210SH-based servers with onboard Intel MatrixRAID configured as raid1. Machines are running 7.0-7.1 i386.
After one server's csup & reboot I've found that according to bios tools raid is degraded, but bootable. FreeBSD begins to panic (fatal trap 12) on boot.
Booting kernel.old doesn't help. Panic occurs immediately after line ad8: '476940MB <Seagate ST3500320AS SD15> at ata4-master SATA150'
Moreover, inserting hdd from this machine on other machine running with 'device ataraid' in kernel causes those machines to panic with same 'fatal trap 12'.
Clearing last 3 sectors from this disk with dd (e.g. destroing raid config) seems to help.

Fix: Unknown
How-To-Repeat: 	Write 3 512-byte sectors from attached file onto last sectors of your disk and try to boot with ataraid

atapicam is no more after FreeBSD 9.x. Long live atacam and friends.
