Hello Jonathan, Unfortunately, I don't have many details about this issue yet. It started to happen only after 5th of August, and I don't remember any major updates near that date. There was only one update which updated some smb packages, IIRC.
Issue usually happens after I boot machine and work for some time. Twice it happened when I was coding in qtcreator, maybe this is related. I also experienced similar problem when booting - but I thought it was a kernel panic related to my webcam (webcam is not new, it is attached for my machine for 2 years), and I don't have stack trace of that case. In order to deduct some trigger I guess it is a combination of high CPU (I donate to BOINC), qtcreator and vnc which is playing podcasts ... I can't repro the issue however ... Will try soon sid and upstream kernel, I had before 3.0 rc7 and it worked well right away. Thank you, -- with best regards, Volodymyr 2011/8/10 Jonathan Nieder <jrnie...@gmail.com> > Hi Volodymyr, > > Volodymyr Shcherbyna wrote: > > > Hello, it seems like my video driver is failing.
