Hi there,

Hardware:   Tyan 2880 (K8S), single Opteron 240
            Adaptec 2200 or 2120, 2 Arrays (20 GB RAID-0, 20 GB RAID-5)


booting the install kernel gives:
[normal boot process]
aacd0: <RAID 5> on aac0
aacd0: 20480 MB (41943040 sectors)
GEOM: create disk aacd0 dp=0xc2dc1c0c
aacd1: <RAID 0 (Stripe)> on aac0
aacd1: 20480MB (41943168 sectors)
GEOM: create disk aacd1 dp=0xc6fa980c
panic: mutex Giant not owned at /usr/src/sys/cam/cam_xpt.c: 4822
cpuid = 0;
Debugger("panic")

I'm sorry for not having connected a serial console. If anybody needs
the full trace information I would gladly reproduce the crash and write
the complete information off.

Yesterdays (2003/11/30) snapshot yields the same result.
