M91p 7033-A1U, updated to Windows 10 Pro x64 and now multiple BSODs per day. I've run the Lenovo driver updates and everything is up-to-date including power management software. Also reset BIOS to defaults. The BSODs seem to be related to sleep mode but not 100% sure about that. The BSOD message is "driver irql not less or equal...ndis.sys". I only have one add-on to the unit, a USB3 card. Anybody else having this or suggestions on how to proceed? I'm considering rolling back to W7.

I have the same problem. WIndows 10 64 bit installed on M91p and I get BSOD a few times a day showing "Critical Structure Corruption" without any further useful infos. I have spent hours troubleshooting and testing with driver verifier and any other solutions posten on the net, without success.
I gave up and went back to windows 7 and the system is stable.
I wounder however, how some manage to run windows 10 on the m91p. There are even vendors who sell m91p with WIn 10 preinstalled.
I can't belive, that m91p is not able to run windows 10.
I hope for a solution. Please if anyone has a solution please post an update on this thread. Thanks!

Exact same problem, Critical Structure Corruption and BSOD. Unfortunately, I'm past the 30 day roll back period (since we went away for 3 weeks). Sounds like going back to W7 is only option. Wish there was an easy way to roll back after the 30 days past.

I have installed a lot of windows 10 on M91p without having any problems. i5-2400
A week ago, a new installed machine getting BSOD:s after 2 hours of testing.
When reading the BSOD-log, I could find that it was related to the system bios.
I had just installed the bios update from 2014 (latest, and recommended) on this machine.
When I installed the earlier version from the same page, the system went stable again.
Page with downloadable files:
Do NOT use the latest, recommended bios with W10 ( 9HKT58A, 29 Jul 2014 )
Instead use the older, 9HKT54A, 01 Nov 2012
After changing to the 2012-version, I hard-tested the system with a couple of 10 hour videos running on youtube + Prime95 for maximum stress testing, and it passed. Using the 2014-version, it broke down within 2 hours.
Lenovo: Please get a bios fix for this. It is still a great machine for giving away to schools / charity
