Comment 1 Pete Zaitcev 2002-05-28 18:06:29 EDT
Andrew, the bug looks fixable, but it's such a pain in the butt
to work with the 2.4.9 branch, that I'd appriciate if you tried
to reproduce this on 2.4.18 that we shipped with 7.3.
You may safely do rpm -i --nodeps, this puts the new kernel
alongside the old one, so you can fix grub.conf. Do not
remove the old kernel or its record from grub.conf!
Let me know if you desire to stay with strict 7.2.
(e.g. an RHN issue or a user request). Thanks!
Comment 2 Pete Zaitcev 2002-07-02 11:52:41 EDT
Did you try a 2.4.18 yet (preferably 2.4.18-5.55 or better)?
Comment 3 Need Real Name 2002-07-29 22:26:16 EDT
I've been unsuccessful in getting the scanner working again with USB, as the
motherboard that I was using started experiencing strange hardware issues a few
weeks after the initial bug report.  The replacement board is older and I've had
to switch to SCSI in order to be able to scan anything.

If I can reproduce in the future, I'll re-open this, but for now the best thing
is probably to close it out.
