Hello Everyone,

I need help resolving kernel panics on a Supermicro X10SLH-F
motherboard in a Supermicro SC-825 chassis.  I originally installed
FreeBSD 9.2 Release/amd64 but kept having kernel panics after varying
amounts of uptime and while running the following command against some
or all of the SATA hard drives in the system:

dd if=/dev/zero of=/dev/ada/n/ bs=100m &

A sample vmcore file is here:


While canvassing the FreeBSD Forums I followed a suggestion to try
10.0 RC4/amd64.  The machine still panicked under the same conditions
at around 27 hours uptime.  The vmcore file is here:


System memory has run Memtest for 62 hours and 47 passes without error
and the chassis has dual 740W PSU's so I think I have memory and PSU
possibilities eliminated.

Apologies if I've sent my plea to the wrong place.  Tell me where to
go and I'll bother someone else.  Thanks, Dan.

How is your swap configured on this machine?

I have a 4G swap partition on the drive containing FreeBSD.
