I might have resolved this BSOD issue, but it's odd, so I'd like to ask for insightful comments as well.
The machine is a stable 10 month old own-build Win 8.1 X79 IB-E workstation based on an Asus X79 Deluxe motherboard. It's heavily stability-tested a month ago, not stupidly overclocked, doesn't run much - or any unusual - software, doesn't have known malware issues, and has uptimes typically 2-3 weeks. There are 6 disks in 3 pairs of 2. I keep backups, but to save time in case of simple disk failure I also run my disks as RAID1 using Intel's onboard RAID.
The background was, yesterday I had a sudden HDD failure. The disk was data only, and making audible "disk head restart" failure noises. I removed the offending disk (confirmed dead!) but a few minutes later noticed that no local hard disks were showing in my SMART program, nor in Windows Explorer, and also Intel RST's utility service had stopped and the application was erroring out on startup. All very strange for an ordinary disk failure. I restarted RST by killing the old process and it also reported multiple disks missing. I might have knocked some cable in testing things, because at that point it rebooted. Upon reboot and CHKDSKing everything, all was normal - so it seemed......
So this morning I have an abrupt BSOD with bugcheck 0x133 (DPC watchdog, param=1). Never had an issue like this before. The event log showed a lot of "unrecognized USB driver" events on restart, apparently from a mix of ASUS/ASMedia/Intel/PCI/no idea. I don't know what to make of that. A quick check of the DMP file with Windbg shows what look like issues related to disk access and paging files, but nothing very specific.
WINDBG STACK OUTPUT:
The references to "LeafPageWorker", "Pool", "ScrubMemory" sound like a fault during paging or something, perhaps an error in disk handling, but not sure. Why, anyway?
Event log, including last 2 events before the bugcheck x133:
I reinstalled the Intel chipset and Intel RST drivers based on these observations. But I'm still not sure what's really happened, and if I've done what is needed. What more I should do? Especially, is this a driver or hardware issue?
Help appreciated!!
