Hi all, After switching from 2.4.22 to 2.6.0-test9, I have received reproducible MCE non-fatal error check messages in my kernel log. (For example, one shows up right after my first scsi card init). >From Dave Jones' patch here: http://lists.insecure.org/lists/linux-kernel/2003/Sep/7362.html and another message here: http://lkml.org/lkml/2003/10/7/214 would seem to imply that Athlons don't like having their Bank 0 poked at, though that's what non-fatal.c does. Would it be correct to make sure that that non-fatal.c starts at bank 1, if it is an Athlon? Dave, is the following patch correct? Booted and tested, no ill effects so far ... - g.
