Description of problem:
After booting phoebe on an IBM Thinkpad T30, kupdated eats 100% CPU for atleast
an hour, happens allways with the mentioned kernel.
System randomly freezes while in console (text) mode. It apears to be related
to simoltaneous usage of USB mouse and keyboard. Once the error occours, no
keys on the keyboard work, and the power button is required.
1st time installing (upgrade of an 8.0 installation that worked just fine with
kernel v2.4.20, phoebe also works fine with this kernel), the system froze just
after installing LVM. After reboot the redhat installer requested to boot the
system normally to do fsck, only problem was that the installer had among other
things killed /bin/sh on this system, so it would not boot; thus fsck had to be
ran from virtual console 2. Continuing the installation after a reboot caused
numerous problems because the installer thought that /bin/sh was present
(according to rpm, bash-2.05a-13 was installed). Some manual cp work + "rpm
-qV" to find broken packages solved these problems.
When installing (over ftp, using the pxeboot images loaded by grub), the
installer insisted on using eth0. There was no option to use the wireless
On suspend (Fn-F4)-resume, the system frequently gets a "hda lost interrupt",
after which the system is unable to access the HD, power-switch is required to
Even after "kbdrate -d 250 -s 30", the keyboard delay before autorepeat is > 1 sec.
Finaly, a request: the installer should be rewritten so that it is easier to
install a small system with only the needed components. This would require a
graphic installer with a smart system for grouping packages allowing one to say
"I don't program in C", "I do program in Python" and thus hide/show relevant
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install phoebe
2. see description
Just tested Redhat9. It hasn't crashed on me yet, but kupdated still eats 100% CPU.
The crash seems to be fixed in RH9.
Booting the machine without noflushd (v2.6.3), CPU usage is fine. If starting
it, kupdated will eat 100% cpu even after noflushd is killed.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
