I have the 3Ware 9500S-4LP (running RAID5) installed in a Dell Poweredge 1800 (dual EM64T Xeon, 7520 chipset). With Fedora Core 4 installed, everything seems fine at first glance. However, after a period (many minutes) of heavy disk I/O operations, the machine begins to slow and then becomes completely unresponsive. I get "APIC error on CPUn: 00(40)" in dmesg which may or may not be related. Nothing is logged to syslog when the failures occur. I have tried booting with noapic and using the uP kernel. Some of these configurations make the APIC error go away, but the hangs still occur. This machine will run fine for days or more at high CPU loads as long as the I/O load to the RAID card is low.
A known issue. Some weeks ago discussed on the CentOS list:

Don't know why the bugzilla ticket is restricted
Very interesting reading - thanks for the link. Some of those posts suggest that the newer 3Ware firmware may "improve" the issue. Otherwise, I guess I'm in the market for a different 4 channel RAID 5 SATA card. Any recommendations?
I am running an Adaptec 2410SA 4 port SATA raid card on x86_64 in FC4 and have had no problems since the third or fourth kernel update of FC3. I recently copied my entire array to another network server, upgraded my firmware on the card and rebuilt the array, and copied everything back... about 200GB. My only trouble is that I can't seem to get the raid tools working. But I haven't really been working on that since about mid FC3.
