Description David Kovalsky 2008-01-16 11:52:52 EST
Unless I blacklist the k8temp module running `sensors' throws out  'General
Parse Error'. I haven't seen this happening on GOLD, since the k8temp module is
new in 5.1.0.


Upstream is well aware of the issue:
...
December 5th, 2006: Note to k8temp users.  The Linux 2.6.19 kernel features a
new hardware monitoring driver, k8temp, which supports all recent AMD K8 CPUs.
The driver will load automatically on supported systems. Due to technical
specificities of this driver, upgrade to lm_sensors 2.10.1 is mandatory. Older
versions of libsensors will fail with a "General parse error" message. If you
can't upgrade lm_sensors for any reason, you'll have to blacklist the k8temp
driver to prevent it from being loaded. Thanks to Artem S. Tashkinov for
notifying us.
...

Version-Release number of selected component (if applicable):
kernel-xen-2.6.18-53.1.4.el5.x86_64
lm_sensors-2.10.0-3.1.x86_64
lm_sensors-2.10.0-3.1.i386


How reproducible:
Always

Let me know if you need any information specific to the system. I will also be
happy to test the patched version on my machine.
Comment 1 Tuomo Soini 2008-03-14 11:20:47 EDT
Tested by upgrading to 2.10.1 and it fixed this issue for me.
Comment 2 Phil Knirsch 2008-04-16 10:40:04 EDT
Rebase lm_sensors to 2.10.1 seems necessary due to the kernel changes.

Proposing for RHEL-5.3 and granting Devel ACK as it should be easily doable for
a minor version change.

Read ya, Phil
