Ok, just got this not so very nice error on a RELENG_6_0 box (built
from sources this morning, GENERIC kernel minus drivers I dont use):

I've been running this stuff in another "test" machine (MSI K8N neo
Platinum, KT333 chip I believe), and I havent had a single problem. I
moved the disks/controllercard to my "real" server 24 hours ago, with
the only apparent "problem" I seemd to have was this:
Nov 17 07:06:12 elfi kernel: xl0: transmission error: 90
Nov 17 07:06:12 elfi kernel: xl0: tx underrun, increasing tx start

Nov 17 07:06:20 elfi kernel: xl0: link state changed to UP
Nov 17 07:06:20 elfi kernel: vlan5: link state changed to UP
Comming and going... these problems just apperade during first 20-30
minutes after boot, then they dissapeared totally (and yes there was
plenty of IO on the net going on both during and after these
messages). Sometimes i just got the first two messages and nothing
"happened", but sometimes the watchdog message came and the network
died for a minute or so.
Here is dmesg from last boot (directly after crash):

The network card is the exact same model as the one I used in the
"test" machine, didn't have any problems there..
So, any ideas what this can be? If there were a disk crash, wish I
have a hard time believing since I ran powermax (maxtor test program)
on both of these disk 3 weeks ago and they have been running fine w/o
a single problem since I started using them, why didn't just GEOM
kick in and run on the other disk? Pagefaulting is not a way to react
if a disk goes dead..
Hope someone can help me/this problem doesn't occur any more... but I
suppose that is to much to hope for...
Thanks
Johan
