From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040612 Firefox/0.8 Description of problem: When booting stock FC2 on a SunFire V20z (dual Opteron) in SMP mode, the kernel sometimes locks up. This seems to be timing-dependent, occurring only when using either the framebuffer console (vga=0x314) or serial console (console=ttyS0). It does not occur when using a plain VGA console alone. It also does not occur with maxcpus=1 on the kernel command line. I will attach a console dump below. Version-Release number of selected component (if applicable): kernel-smp-2.6.5-1.358 How reproducible: Sometimes Steps to Reproduce: 1. Install FC2 on a SunFire V20z. 2. Edit grub.conf, adding console=ttyS0 to the kernel command line. 3. Boot with the SMP kernel. Additional info:

Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
