Red Hat Bugzilla – Bug 34746
clock timer configuration lost messages
Last modified: 2007-04-18 12:32:32 EDT
I'm seeing the issue described below on my Dell PowerEdge 2400 running
qa0401, kernel 2.4.2-0.1.49-i686smp. Perhaps it's not restricted to VIA?
System has 2x933MHz, 1GB RAM.

Small number of VIA 686 boxes randomly jump from 100Hz back to the DOS 18Hz
timeout. We dont know if its hardware or maybe APM bios bugs. The kernel
puts the timer back and life appears happy again
Somehow serverworks machines seem to trigger the message. It's harmless
and the print-priority has been reduced (eg KERN_DEBUG) for newer kernels.
Severworks either has a similar flaw, or a known problem in the code triggers.
The test is slightly inaccurate as there is a small windows during "counter
overflow" where the detection goes wrong. Setting the clock to 100Hz is
harmless if it is already 100Hz so there is no harm done.
We have reduced the priority of the printk to below "user visible" -> resolved
