I'm unable to boot kernels 2.10[56] due to the following failure during
SCSI device scanning; kernel 2.102+io_apic behaves as expected.
Hardware: TYAN TC II, 2xP200, BusLogic-UW, AHA2940 (plain) as 2nd controller.
BusLogic's initialization is successful (time and kernel infos removed) :

AHA's device scan fails miserably (and this has been written to paper):
(scsi1:0:-1:-1) Scanning channel for devices.
scsi: aborting command due to timeout: pid 20, scsi1, channel 0, id 1, lun0\

scsi host 1 abort (pid 20) timed out - resetting
scsi bus is being reset for host 1 channel 0
scsi host 1 channel 0 reset (pid 20) timed out - trying harder
The last three lines are repeated forever ... ;-(
2.1.102+io_apic scans at this stage like a charm:
