Got an issue with the APIC, SMP and possible MD code - I've got this dual Athlon box with two Promise Ultra100TX2 cards. Each has two IBM disks on it, for a total of four. I use the RH7.2 installer to install software raid 0, and everything works fine! No errors, nothing. Absolutely perfect. When I boot the *real* kernel, however, I get a number of things: - I/O errors to hdi and hdk (the two disks on the second promise card - which isn't UDMA because the ports can't be probed. The two disks on the first are UDMA - never any errors on those) - Spurious interrupt #7 - APIC error - AMD Errata #22, try noapic. The thing works perfectly in single processor mode, by the way. I also tried noapic (although I still get the message to try noapic! Does this flag do anything!?) and also tried changing two bios options - the MP table to revision 1.1 or 1.4, and this strange option to "use IRQ table entries in MP" or some such thing. I tried both options, on and off, and I still get these errors. It seems to be apic related - anyone out there have any ideas on how I might get it working!? I also tried 2.4.14 to a limited fashion, but since he I/O errors corrupt the fs, so I can't try too many things before I have to re-install! Thanks!! -Jeff.
