I'm getting a blue screen of death on shut down of my Windows 7 VM. It seems to have started since upgrading to Parallels 7. The info on the BSOD is varied, although it started out with DRIVER_IRQ_NOT_LESS_OR_EQUAL, with the offending file being iastor.sys. Now it has gone on to other errors and files. I've done basic troubleshooting. Safe Mode causes the same BSOD, so it doesn't appear to be a driver issue. I'm thinking it may be a Parallels 7 issue. By the way, it happens on both my Macs. It may also be my VM, but I wonder if anyone else is having a similar issue before I tackle reinstalling the VM?
