Description of problem: The TSC timer was disabled in rhel 3. Please resolve the underlying issues, and re-enable it. There are several opteron hardware platforms which do not provide HPET timer. Customers require high-resolution timers for correct application behavior. There are also platforms with problems with the HPET timer, where fallback to TSC is required. Note that sles8, sles9, and rhel4 all do not disable TSC. Version-Release number of selected component (if applicable): rhel 3 update 4
Don, can you give your input as to whether this warrants a kernel fix or if the workaround is satisfactory for the next release?
How can it be a workaround, if it doesn't work properly
This still seems to be a problem as of Update 5. What's the status?

TSC was disabled at AMD's request on opteron based systems due to the fact it cant safely be used with their PowerNow technology. PMTimer support was added to RHEL3 to address this issue, and is the preferred timer on AMD based systems.
