>Description:
Hello,

We have problem with random kernel panics every few days. More information on the attached screenshot from KVM - http://wstaw.org/w/lji/. OS version is reeBSD 8.2-PRERELEASE #12: Thu Jan 20 15:21:17 CET 2011.

Probably the solution is this - http://svn.freebsd.org/viewvc/base?view=revision&revision=212803, but regardless planned MFC is still out of 8-STABLE.

Is it planned to add this patch before final release of 8.2 ?
