Dear ILUGC,
Of late, my machine has been freezing sporadically with some
error. Though I have tried Googling the error, I have not been able to
get a satisfactory diagnosis of what the cause could be. Therefore, I
was wondering whether someone on the list could interpret the message
better.
Please note that I was using the NVidia provided drivers for the Riva
TNT2 card. I have currently disabled it, but have reason to suspect
that these crashes are independent of that. Also, I am using
reiserfs. I get the error with both the stock Debian Etch kernel
2.6.18-4-486 and a custom compiled 2.6.21.1. Is it a software problem
or a hardware problem?
Here's the relevant part of the syslog during that crash (when the
NVidia driver was present):
