Too Slow - what'd I break?
Howdy all.
I've converted a Pentium II-350mhz w/ 128M RAM workstation from Windoze
to Debian. Unfortunately, it seems that many operations are far slower
- especially disk access. I've pasted the output of <dmesg> below. I
do see some error messages regarding VFS mounts. I also see errors
regarding <devfs> mounts during bootup that are not shown in the <dmesg>
output - I'd also appreciate knowing what these bootup messages are
indicating and how to fix 'em.
This is using the latest unstable kernel-image-2.4-686 package, as well
as the lowlatency and preempt patches.
