Description of problem:
Booting 2.4.18-4 kernel on ALR Evolution MP system (dual Pentium) with DPT
SmartcacheIV (DPT 2024A) SCSI controller causes loops in DPT EATA/DMA code. 

Version-Release number of selected component (if applicable):
Kernels 2.4.18-3smp or 2.4.18-4smp (2.4.9-everything seems to be fine).


How reproducible:
Always

Steps to Reproduce:
1. Boot 2.4.18-3smp or 2.4.18-4smp kernel on such a system
2.
3.
	

Actual Results:  scsi0 : EATA/DMA 2.0x rec 6.50.00
EATA0: 2.0C, PCI 0x9010, IRQ 14 BMST, SG 64, MB 64
EATA0: SCSI channel 0 enabled, host target ID 7
  Vendor IBM      Model: DCAS-32160     Rev: S65A
  Type:  Direct-Access                  ANSI SCSI revision: 02

EATA0: abort, mbox 2 is in use
EATA0: abort, mbox 2, interrupt pending
EATA0: reset, enter, target 0.2:0, pid 2
EATA0: reset, locked mbox 2 forced free.
EATA0: reset, mbox 2 in reset, pid 5
EATA0: reset, board reset done, enabling interrupts
EATA0: reset, interrupts disabled, loops 94762
EATA0: reset, mbox 2 locked, DID_RESET, pid 6 done
EATA0: reset, exit, pid 6 done
EATA0: abort, mbox 2, target 0.0:0, pid 5
EATA0: abort, mbox 2 is in use
EATA0: abort, mbox 2, interrupt pending
EATA0: abort, mbox 2, eh_state timeout, pid 5
scsi: device set offline - not ready or command retry failed after host reset:
host 0 channel 0 id 0 lun 0

and so on with changed values  of pid and mbox

Expected Results:  Boot corectly as with an UP kernel or the SMP one without
APIC support.

Additional info:

The problem doesn't occure when I pass 'noapic' option as a kernel parameter.
