Hi,
I got a panic on an i386 5.4-STABLE around Aug 28 with SMP enabled.
It has 2 physical CPU with HTT enabled (so, total 4 cpus).
This is a NFS server only with external scsi raid attached.
The console log, kgdb output and sysctl.conf are as below.
I'll keep this core and if someone is interested, I can send any other
information requested.
Regards,
Rong-En Fan
