fglrx will not load: KCL_AtomicTestBit

[grutz]

Hey guys, I'm having a terrible time trying to get any fglrx driver to install on my Tyan FT72-B7015/S7015 system. Hopefully somebody else has seen this or can pinpoint to what's up. The host OS is Ubuntu 12.04.2 LTS Server and I've tried the 13.1 and 13.3 beta AMD drivers.

Hopefully it's something I've just missed or messed up during the installation. Pretty bare bones / followed the wiki / not much going on here!

[epixoip]

of course the glaring null ptr deref there is a pretty big indication of a bug in the driver, but i can't say any of us have experienced that.

have you tried testing each gpu individually, or two at a time, three at a time, etc?

[epixoip]

what kernel are you using, by the way? all of my systems are on 3.2.0-39-generic. it could be that a more recent backported patch was introduced that has broken compatibility with 13.1

[grutz]

Yeah, I haven't started swapping out cards yet but I have a suspicion one may be bad. The server is at a remote location so I schedule some time next week to swap things out when I'm on-site.

Kernel is 3.2.0-29-generic #46-Ubuntu SMP and apt-get was 'holding back' linux-headers-server linux-image-server linux-server. I just did an 'apt-get dist-update' to get to 3.2.0-40 but the system didn't come back from a reboot. Will report back later.

[epixoip]

haha ok. we've had some growing pains with one of our FT72B7015's as well, and what we ended up doing was pulling it out of the rack and leaving it at the office for a few days until we could work out all of the kinks. i would suggest doing the same, and don't rack it back up until you're 100% sure everything is working correctly and you've done thorough testing.
