Panic with amr and 5.4-PRERELEASE

Hi,

I have a FreeBSD bi-processor box with amr device in FreeBSD
5.4-prerelease of this week.
# uname -a
FreeBSD sokaris2.u-strasbg.fr 5.4-PRERELEASE FreeBSD 5.4-PRERELEASE #3: 
Thu Mar 10 15:33:01 CET 2005 
root at crc.u-strasbg.fr:/usr/obj/usr/src/sys/SOKARIS2  i386

Starting a program which continuously polls the state of the raid array
(amrstat, see source attached), and making a buildworld at the same time
triggers a kernel panic. The problem is fairly easy to reproduce.

Features added in the SMP kernel : altq, KDB, DDB, GDB (see config file
and dmesg output attached). The kernel is launched with ACPI disabled.

A stack trace of the kernel panic and the result of a remote gdb follow.

Thank you by advance for your help,

Philippe PEGON
