NR CPUs is set to 32, theoritically the OS should be able to enumerate 12 CPUs
In older RHEL kernels (2.6.9) a large-smp kernel had to be used to enumerate >8 core count systems. However I wouldn't think that Fedora 10 would have such limitations. Modifying steps to reproduce, as there is an issue installing the OS on Toonie. Steps to Reproduce: 1.Install Fedora 10 32-bit 2.Install fails This was fixed in an update, kernels after 2.6.27.15-170.2.20 will detect up to 32 processors. Great. I'm not familiar with Fedora updates; I need a link or instructions to pass on to AMD QA. Thanks, Bhavna (In reply to comment #5) > Great.

Or install the latest respin if you want to test new installs: http://fedoraunity.org/news-archives/fedora-unity-releases-fedora-10-re-spin I can't help with how to download the respin and make the install discs though. Marking this bug as fixed by the kernel update, reopen the bug if it doesn't work. |
