Hello,
Since upgrading my system to a 2.2.14 kernel I've had it crash three times.
(Two times today alone.) All three crashes report an "unable to handle
kernel paging request" before dying. This machine has been stable with a
variety of kernels for over 2 years. It has never once paniced prior to
this kernel release.
Any ideas?
-Kevin
Output from "dmesg | ksymoops":
ksymoops 2.3.3 on i686 2.2.14. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.14/ (default)
-m /usr/src/linux/System.map (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.
Warning (compare_ksyms_lsmod): module nfs is in lsmod but not in ksyms, probably no symbols exported
Warning (compare_ksyms_lsmod): module nfsd is in lsmod but not in ksyms, probably no symbols exported
