Something like this may be happening. I wonder if the LBAsect numbers in the
error messages are from sectors larger than the disk or partition supports. It
is a 10GB HD but only 1GB of root fs for The Hurd of course.
Error messages only occur when GNU Mach is booting.
I did upgrade The Hurd to the one in the Debian pool this morning using dpkg on
files that were copied into /gnu/home on the Linux side. The SiS 630EC
(embedded controller(?)) version of the SiS 900 ethernet does not seem
supported by GNU Mach. Is this right? What would be the best way to add
support--port the driver to GNU Mach or switch to OSKit and use the Linux
driver?
