I will start with, I suck at linux.....
The SELVIEW tool (which i can't seem to locate for this board.It should be on the resource CD). will give you a much better picture of what is occuring.
IPMITOOL does not report all the values that get logged which leaves you guesing.
So here is my guess,
18 | 11/16/2012 | 05:15:36 | Unknown #0x85 | State Asserted --- Something stopped responding. could be ablut anything. Hence UNKNOWN,
2c | 11/16/2012 | 05:15:37 | Critical Interrupt #0x07 | Bus Uncorrectable error | Asserted - System attempted to recover and can't. Blue screen (execpt that your in Linux)
I would try removing any add in cards and run far a bit to see if the error goes away.
If so, add the cards back until you start getting the error again.
Thanks a lot for your help. i managed to install the ipmiutil and now one of the errors seem more readable:
0018 11/26/12 08:05:49 CRT BMC SMI Timeout #85 SMI asserted 03 [41 0f ff]
002c 11/26/12 08:05:49 CRT BMC Critical Interrupt #07 Bus Error 6f [88 08 ff]
i will try to google for the new CRT BMC SMI Timeout #85 SMI asserted 03 [41 0f ff]. as SELVIEW or the resource CD are not available for download.
