kernel output with oops
We just received a similar system for testing in our lab (S2885 - same chipset,
more features). We installed 6G of RAM and were able to successfully install
and run the RHEL3 release candidate. Did this bug show up every time you
booted? Have you tried the latest release on it?
We have not duplicated this bug in-house, and the customer has not
supplied any more information; changing status to NEEDINFO.
No update from customer, and I suspect this may be a combination of
firmware and MTRR parsing issues that we persued with Tyan and AMD
(see Bug 118556 among others). Closing this as CURRENTRELEASE since
this platform should be working now.
