[Bug 363900] Re: [i945GM] X.org freezes with intel driver, no apparent trigger

[Aaron Roydhouse]

One of Steve's freezes looks very similar to:

I've been having similar sounding freezes since upgrading from Intrepid
8.10 to Jaunty 9.04 (amd64) on a Lenovo X301 (2776) laptop. In the 24
hours since upgrading it has twice locked up the screen display, mouse
pointer, and keyboard. /var/log/kern.log shows a kernel 'Oops' related
to 'i915_gem_execbuffer' - might be a separate bug or different error
for same problem?

(is this like a 915/945/965? the kern.log mentions 915)
