BSOD 'BAD_POOL_CALLER' in Windows 10 #8

This happened while a lot of I/O was directed to my temp folder, which is symlinked from %AppData%\Temp and %WinDir%\Temp to a folder on an ext4 volume.

Pardon the horrible formatting, that is github's fault for not supporting something line [code]...[/code].

If you have a pdb file with debugging symbols available, I may be able to get you some more details, since the instruction pointer was suggested to be completely inside ext2fsd code. Note: this is not consistently reproducible; apart from this one-time event, I have never had a single issue with ext2fsd. Still, I have this 800 MB crashdump, and if it can help improve ext2fsd, I would be happy to invest some time in playing around with said crashdump.

Thank you very much for the awesome software!

I will join in, similar bug check 0x4E: PFN_LIST_CORRUPT with argument 0x07 during high activity.

A driver has unlocked a certain page more times than it locked it.

Edit: I should add that I later noticed the disk was severely end of life with 1037 defective, but no remapped, sectors. Kudos to ext and ext2fsd for being able to work on it in the first place.
