I have a Windows Server 2008 R2 w/ SP1 that started BSOD every hour. Attached is a photo of the blue screen. Here are the details.
When the BSOD happens, a memory dump cannot write to the disk because the disk is not available (I believe).
When the BSOD happens, you have to do a cold boot because if you do a warm boot the boot Raid mirror is not found.
The Adaptec controller drivers were downloaded and updated from the manufacturer (SuperMicro) but that didn't help.
Several hotfixes pertaining to storport.sys were installed but that didn't help.
Opened a ticket with Microsoft and spent 6 hours on the phone with them to no avail.
The Microsoft tech used a program called "NotMyFault" or something like that to cause the server to crash and create a BSOD. The purpose of that was to see if a dump file would be created. It did create the dump file successfully. That confirms in my opinion my previous thought that the problem may be the onboard controller stopping to function. Like a memory leak but I installed the hotfix pertaining to memory leaks and storport.sys
Anything I try requires me to wait for the 60-62 minute time frame to expire before I know if it worked.
