I'm attempting to upgrade to kernel-smp-2.4.21-27.0.4.EL (x86_64) on a Dell 1850. The new kernel is panicing on reboot. When comparing against the current working kernel, I just noticed that we're currently running the "UP" kernel:
[root@polaris root]# uname -srvp Linux 2.4.21-27.0.2.EL #1 SMP Wed Jan 19 11:49:43 CST 2005 x86_64
First question... why is the kernel version reporting as SMP when this is the UP kernel package? I thought it might have something to do with HT, but no, it's seeing both processors:
[root@polaris root]# cat /proc/cpuinfo | grep proc processor : 0 processor : 1 processor : 2 processor : 3
Second question... has anyone else experienced problems with kernel-smp-2.4.21-27.0.4.EL on x86_64? I installed the newer kernel and it paniced on reboot. I'm offsite without console, so I'll be going in tomorrow to take a closer look. Just FYI, here is the information on each kernel we're working with:
