Hi all:

I have the following hardware running FreeBSD 4.3-Release and
get a kernel panic after running make -j 30 buildworld for sometime.
Any ideas what's happening? Also, I can't even boot this box with
4GB RAM. Same problem was posted earlier by a person with IBM
server... I tried changing NKPT option only to find out it's not
a valid option in 4.3-R

Dual PIII1Gz, 2GB (2x 1GB) ECC RAM
Supermicro DER mobo
Mylex AcceleRAID 170 running RAID 5

both RAID controller and harddrives have write cache disabled.
I do have softupdates enabled on the partition where i'm building
world

/kernel: Fatal trap 12: page fault while in kernel mode
/kernel: mp_lock = 00000002; cpuid = 0; lapic.id = 00000000
/kernel: fault virtual address = 0x0

/kernel: giving up on 1 buffers

/kernel: mly0: flushing cache...done

Any help would be appreciated.

Thanks in advance.
