Just a quick post this time:
Everything ran mostly smooth after removing Windows 7 and switching to Windows 8 Consumer Preview. I hate using virtualization on a desktop, but I wanted to try out Hyper-V 3.0 also.
After a few weeks my laptop started acting up. Random reboots, and system halts whenever I’d put it to sleep or hibernate. Not good, Windows – definitely not acceptable.
I wasn’t sure what caused the issues, since the error codes didn’t give a specific reason, just the typical IRQL_NOT_LESS_OR_EQUAL errors.
The reason could be one of the following:
Running Hyper-V 3.0 on a laptop – not a far-fetched thought. Considering there were some slight issues to get Hyper-V running when your regional settings are not US English, this was my first suspicion.
Any of the random hotfixes Microsoft pushes through Windows Update – There were plenty, and I wasn’t really sure which of them did what. Didn’t have time to investigate.
IIS + SharePoint + SQL Server 2012 – These are fairly well-behaving citizens on the operating system so I didn’t inspect these further.
3rd party hardware drivers – Mostly I used native Windows 7 64-bit drivers from HP’s support site. A few were Microsoft’s own (apparently experimental) drivers and a few from vendors.
Eventually the issue boiled down to NVidia’s drivers. There’s a nice write up on this at istartedsomething.com but the fix is not nice – effectively disabling most of your GPU abilities to do something doesn’t feel like a fix to me. A lot more insights at the Neowin.net forums here.
So for now, I’m back to Windows 7 on my laptop and hoping for Nvidia to come up with a proper release for their GPU driver. Alternatively I could go back to the Intel GPU drivers available here.
