Comment 200 for bug 561802

Andy, I tested the kernel located at http://people.canonical.com/~apw/lp561802-natty/ on my Dell Latitude E6510, 2GB, 64bit, Intel graphics. My distribution is Ubuntu 10.10.

First: Your version seems to be working fine. No issues whatsoever up to now. I'm booting and using it with an external second monitor attached via the display port (resolution: 1600x1200). I will add another report here in some minutes regarding a boot without a second monitor.

I also tested all other kernel versions discussed here which were coming as a .deb package ready for download (i. e. I did not test all patch versions). Before the kernel pointed to by you I was using a .35 kernel. With 2.6.38-997.201102020913 and 2.6.38-997.201102081238 I had stability issues after some minutes (without a second monitor after some hours): X just crashed and I had to relogin. I was under the impression that it had trouble handling X sessions with a lot of stuff going on, maybe memory leaks.

No such issues with the 2.6.38-4-generic_2.6.38-4.31~lp561802v201102162013 now. I tried to crash it by opening about a hundred windows, using fancy Compiz extensively, running flash applications, Youtube videos, 3D applications etc. but to no avail :) Uptime now is 44 minutes and everything seems to be just fine.

Also suspend/resume worked without issues. I did not test hibernate (to disk).

I will check booting without a second monitor now, just to make sure, and report back here.

Alfe
