SubjectRe: All kernels after 2.6.32-git10 show only 1 CPU ** Fixed in 2.6.33-rc2 **
Something is weird on the 2P box. Using the openSUSE kernel
2.6.32-3-default and early 2.6.32-git kernels on the 2P box, I see 2
processors. Same if I boot from the install DVD.
Using 2.6.32-git10, 2.6.32-git15, 2.6.33-rc[12] the box hangs solid at
various places during boot.
When I first booted up 2.6.33-rc2 after using the openSUSE 2.6.32-3
.config as the basis for "make oldconfig", the kernel booted fine with 2
CPU's, second and subsequent reboots, it locks up solid.
Later I shall try to get some output from a serial console.
tindog:/usr/src # uname -r
2.6.32-git1-smp
I shall also progress through the kernels to see exactly which
introduces the problem where a kernel will boot one time and not other
times and why only one CPU shows when those kernels boot.
Regards
Sid.
