Today I recieved a rather unexpected critical stop while working away on my desktop doing the same thing I do every day of the year (ftp, ssh, txt editing, browsing, irc, im). For whatever reason it did not generate a log in event viewer as they usually tend to. There has been no recent updates or installations in the past month or so other than this and last month's automatic updates. However, I did remove kaspersky antivirus from the system the other day in preperation for getting around to moving over to Nod32. Fired up windows debugger and checked the minidump. I doubt the OS component, win32k.sys in this case, is at fault unless the most recent updates or kaspersky's uninstaller broke something. Any chance I can figure out what driver passed a bad instruction when calling win32k.sys from this dump? http://ankle.sinistrals.net/misc/files/Mini122706-01.dmp Here are the loaded modules:
