Description Jordan Russell 2004-04-11 01:11:19 UTC
Description of problem:
The microcode update works fine with RHL9's kernel-utils package
(2.4-8.29) but gives an error with FC1's kernel-utils package
(2.4-9.1.101).

Version-Release number of selected component (if applicable):
kernel-utils-2.4-9.1.101.fedora

How reproducible:
Always

Steps to Reproduce:
# service microcode_ctl start
# cat /var/log/messages

Actual Results:

Apr 10 19:58:09 fishy kernel: microcode: collect_cpu_info : sig=0x683,
pf=0x10, rev=0x14
Apr 10 19:58:09 fishy kernel: microcode: error! Bad data in microcode
data file
Apr 10 19:58:09 fishy kernel: microcode: Error in the microcode data

Expected Results:

When I downgrade to the kernel-utils package from RHL9, I get this
(which is correct):

Apr 10 20:02:38 fishy kernel: microcode: collect_cpu_info : sig=0x683,
pf=0x10, rev=0x14

Additional info:

I'm testing with a PIII 800 CPU.

Comment 1 Jordan Russell 2004-06-02 02:20:34 UTC
After upgrading to Fedora Core 2, this problem has gone away.
I now get "No suitable data for cpu 0", as with Red Hat Linux 9.
