Just a +1 for this.
Upgraded from kernel 12.2-RELEASE-p7 to 12.2-RELEASE-p12 with freebsd-update on
several systems both amd64 and i386. Some of the i386 systems now panic under
disk load (backups!). These are otherwise very lightly loaded web servers or
firewalls.
Is this related to Bug 261338 ?
Example panics from three systems (cut-and-paste from dmesg) below:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
