[Bug 539609] Re: i915.powersave causes hangs particularly following suspend/resume on i945 and older cards

6th of May 2010

For me, this bug has not, repeat NOT, been solved.

I use a Toshiba A80 laptop with a i915 graphic card. My Ubuntu experience with it is not too good...
- Jaunty: faulty driver release, after some weeks, I downgraded to driver 2.4
- Karmic: computer can't be used for suspend to RAM during the full time of this release, i.e. six months
- Lucid: the same (one week).

I have now the normal kernel 2.6.32.22.23 and, after resume, I always
experience a freeze between 10 minutes to 40 minutes. Sometimes, I am
informed that I must switch to low resolution mode, sometimes it's just
a black screen...

I've upgraded to kernel 2.6.33.3 but I've the same result.

This bug has NOT been solved. Thanks for help.
