Hello,
I am finding stability problems running the 2.4.20-30.7.legacy kernel on
Redhat 7.3. The problems seem to be more prevalent on Intel Bayfield
hardware. On a test system, I have updated the BIOS, removed all non
essential loadable modules (lm_sensors, scsi-ide) and tried stopping non
essential services, but the system will still crash once every 2 days or
so.
Attached below is the crash information captured via a serial console
connection.
Is this information useful as is, or should I provide more details?
Best Regards
johnny

ksymoops 2.4.4 on i686 2.4.20-30.7.legacy. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-30.7.legacy/ (default)
-m /boot/System.map-2.4.20-30.7.legacy (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.
