It looks like the driver recovers fine.

SERR must be enabled by your BIOS. I will change the driver so that, should the memory mapped I/O test fail, an SERR (and thus an NMI) is not generated.

These are left over from the failed memory mapped I/O test. They should have been cleared by the test, but the behavior must be different for the 7896/97. I'll review the documentation for this chip and see if I can quiet up the failure.
Just out of curiosity, do you have any strange PCI options enabled in your BIOS? I remeber seeing memory mapped I/O failures on this ServerWorks chipset under FreeBSD in the past, but an updated BIOS resolved the issue for the affected users. It seemed that the BIOS incorrectly placed the Adaptec controller in a prefetchable region.
