Something weird after installing Catalyst 11-6

[OCedHrt]

I was on 11-5 with my 4850 and everything was running fine. I upgraded to 11-6 and the following weird things happened:

1. I used to run work size of 64. Now, any work size < 256 crashes the miner in MSVCR90.dll. Any gpu miner. This can be phoenix, diablo, poclbm, whatever. CPU mining is not affected.

Code:

Faulting application name: phoenix.exe, version: 0.0.0.0, time stamp: 0x4918019b
Faulting module name: MSVCR90.dll, version: 9.0.30729.6161, time stamp: 0x4dace5b9
Exception code: 0x40000015

2. However, the miner works ONCE without vectors and once with vectors regardless of work size. Even after rebooting it doesn't work. I ran it with poclbm at work size 64 with and without vectors and now I can't run them with work size < 256. Here's a phoenix example:

Above, I run with worksize 1024 (too large?) and get ~66MH/s. Then I run 64 with vectors. With vectors because I already ran it without vectors and that doesn't work anymore. I then abort it and run it again: crash. Work size of 256 still works.

3. There used to be a performance hit at work size 256 (and 128) but I'm not seeing that now. Don't have current numbers for work size 64 to show it though.

REINSTALL DRIVER. that is all

REINSTALL DRIVER. that is all

Tried a normal reinstall but not a full reinstall with clean uninstall. But, worksize 256 >= than worksize 64 on 11-5 catalyst so it's not a big deal yet.

Was having the same problem with a 4870 but not with a 5970 on the same machine, removed worksize from all the miners (including the 5970) and actually gained 10MH/s.

i had a problem witg the new catalyst too, it "stole" 60Mh/s from my 6950 - simply went back to the previous driver version
