I'm being constantly frustrated with this issue, and I'm still not sure the best way to solve it.

I have my ubuntu server running headless with cgminer, and it is configured to automatically take security updates. However it keeps updating kernel versions that break my existing and working radeon drivers. When it does so, I am forced to update the driver. I was at a state where everything was working fine with APP 2.6, however this morning I had a power outage and when the server came back up, cgminer segfaulted.

It seemed that this was due to a kernel incompatibility, which required a driver update. I tried a minor update, which wouldn't install due to some kind of DKMS issue. Only driver that installs is catalyst 13.4. So I updated the driver, seg fault goes away. But now I get the dreaded invalid nonce error (like I've had in the past.) Tried reinstalling APP 2.6, and I get a seg fault. So, I update to app 2.8; no more seg fault, but now I get nonce error.

I like automatic security updates because this server IS exposed to the public internet (its only exposed port protected by FWKNOPD though,) but these compatibility breaking kernel updates have finally done me in, so I'm turning it off (It would be nice if it security updated everything *but* the kernel, and notified me if a very serious vulnerability was found and is in need of immediate attention - otherwise none of these updates have ever been truly needed.)

Having said all of that, is there any known working driver/app sdk combo that works with the 3.7.0-7-generic kernel and bitcoin mining? By the way, this all happens with bfgminer too, old versions and new.

Alternatively, is there a way I can get DKMS installation to work when I install older amd drivers on newer kernels?
