Hello, 

I'm trying to build a new server and I keep getting spontaneous reboots that seem to occur during heavy disk IO.  The error just before reboot is:

    Panic: ffs_valloc: dup alloc

My first suspicion was a hardware problem, but I have swapped *everything* out (mobo, disks, cables, CPU, RAM, floppy, NIC) and it still happens.  I have logged temperatures and reboots have occurred as low at 34°C.  Curiously enough, I built another box with identical hardware a few months ago and it's happily chugging away down at the colo.  NJow I'm thinking that I have some messed up setting in the BIOS, but without the other machine on hand to compare...

Here's the hardware:

    ABit SE6
    Celeron 633
    2 x 128M PC100
    2 x IBM 46G ATA100
    Intel 10/100

I have experienced this with 4.1-R, 4.2-R and 4.2-S from a month or two ago.

I have a core from the crash, but no kernel.debug to compare to.  It's a GENERIC 4.1-R kernel.

    - H
