From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc3 Firefox/1.0.6 Description of problem: The 64 bit 2.6.12-1.1372_FC3smp kernel is seriously broken. It gets and oops when spawning processes. I first noticed it when opening a shell in Xemacs. I've now got a much more reproduceable case. Doing a make -j 2 on the 2.6.12.4 kernel I reliably get the oops. The system that I running on is an Athlon 64 X2 4400+, 4G DDR, MSI K8N Neo4 mother board. Running 64 bit FC3 with all of the available updates. Version-Release number of selected component (if applicable): 2.6.12-1.1372_FC3smp How reproducible: Always Steps to Reproduce: 1.make -j2 all on the kernel 2. 3.
