panic: pcib0: uncorrectable DMA error AFAR

[dcx dcy]

Hello all,

              I was running FreeBSD 9.1 Stable on my server and I decided to upgrade to 10 STABLE two weeks ago.

 

The upgrade worked fine, but then the server was randomly crashing many times a day. 

 

I tried to upgrade to another 10 STABLE version and it did the same.

 

I had to revert to 9.2-STABLE (r262480) and everything is fine with this version.

 

Here is a summary (GENERIC KERNEL + PF & ALTQ):

 

FreeBSD 10.0-STABLE FreeBSD 10.0-STABLE #0 r261732: Wed Feb 12 20:45:17 EST 2014
