Kernel Opps when running any Cell Application on >=2.6.22.1-41.fc7
Last modified: 2008-02-15 21:35:50 EST
Description of problem: On kernel 2.6.22.1-41.fc7 when ever a Cell application is run it locks up and a kernel oops is produced. The system still works and I am able to just ssh into it(I'm running it headless) but I still can't kill the Cell applications that have frozen. Cell programs run fine under 2.6.21-1.3228.fc7 Version-Release number of selected component (if applicable): Kernel: 2.6.22.1-41.fc7 Cell SDK: 2.1 Hardware: Playstation 3 How reproducible: Run any Cell application Additional info: DMESG kernel BUG at arch/powerpc/platforms/ps3/spu.c:500!

Can you try a kernel from Koji? http://koji.fedoraproject.org/koji/buildinfo?buildID=14800
Was Koji's kernel pushed out? I did an update tonight my kernel was updated to 2.6.22.4-65.fc7 which is the same as Koji has. In any case 2.6.22.4-65.fc7 has the same problem.
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged.
It still happens on all recent kernels. I havn't had time to really debug this myself but I will try to help as much as I can.
Thank you for the update Lee. If it is still happening on a kernel from rawhide, it is probably a candidate for taking upstream. I am happy to file a bug at the kernel.org bugzilla for you on your behalf if you wish. Cheers Chris
Hello Lee, Could I trouble you for an answer to the above? Again, I am happy to file at the kernel.org bugzilla on your behalf with the information you have provided if you are willing to be cc'd into that bug. Cheers Chris
Closing as per previous comment. Please re-open if this is still an issue for you.
