I've been slowly working to isolate the source-code at the root of this
error. The biggest problem I faced was the sheer number of errors
reported at boot-time swamped the kernel's log buffer (128KB by default)
and therefore I had no information about what was happening in the lead-
up to this.
Yesterday I built a new kernel with the kernel log buffer size increased
from 128KB to 1MB.
This is with Edgy Eft versions 2.6.17-10-generic and 2.6.17.14.
Using make menuconfig I changed the Kernel Hacking Kernel Log Buffer
size. I altered the log-buffer-shift parameter from 17 to 20. This is a
bit-shift value, so the buffer size is 2^X.
The entry in the kernel configuration file .config is
CONFIG_LOG_BUF_SHIFT.
Now finally I have the kernel messages leading up to bug:
