I have an old laptop I'm trying to resurrect, and am having a strange problem:
If I run the kernels supplied by Xubuntu, all is well - no strange behavior (as in, none of the stuff I am about to describe happens).
If I build my own kernel (as I am trying to strip out unneeded stuff this machine does not and never will have like AGP and Bluetooth), weird things happen: For 2.6.25, I cannot read or write to /proc/mtrr - I get an I/O error (the file exists within proc) Starting klogd hangs for about 2 minutes - looking at the system during this time shows a "dd if=/proc/kmsg of=/var/log/kmsg" process hanging. Attempting this by hand shows dd hangs (as does a "cat /proc/kmsg").
Other than this, the system runs (networking comes up, X comes up (eventually).
I've tried just building with the kernel configuration Xubuntu uses to the same results.
I would think that the fact that the Xubuntu supplies kernels work would tend to exonerate the hardware, that building with the Xubuntu supplied configuration would tend to exonerate the configuration, but that leaves me stumped - either my version of GCC is screwy, or my build process is bad, or ???
(builds are done on my Athlon Ubuntu machine ( GCC version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) via the standard "make gconfig; make" process on a tarball pulled fresh from kernel.org, which is then NFS mounted by the target, a final "make modules_install install" executed, and the initrd created on the target).
