Hi there,
starting from 2.6.10 our 32-bit Kernel refuses too boot our Dual Opteron
Machines. 2.6.9 worked fine though.
Here is the oops I get (vanilla Kernel, .config attached).
--cut--
ksymoops 2.4.3 on i686 2.6.11-rc1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.11-rc1/ (default)
-m /boot/System.map-2.6.11-rc1 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
