Description Jon Smirl 2003-10-26 00:59:26 UTC

Description of problem:
I have SCSI and the ICH5 SATA drivers built into my kernel. Uniprocessor this
works fine. The OS install kernel also works. 

The default SMP kernel does not work. Same for a custom one I have built trying
to select all the appropriate options. The SATA driver comes up and assigns the
SATA drive IRQ 17. When the partition is probed I get DMA timeouts. I am pretty
certain that there is some problem with ACPI getting IRQ 17 configured
correctly. I can't capture the dmesg since it won't boot.

2.6-test9 works without problem smp and uni. 2.6 requires full ACPI support for
SATA to work in SMP mode. I am using SCSI ATA support in test9 too.

Machine is Dell PE400SC with one SATA and one IDE drive. Hyperthreaded CPU used
for SMP mode. i875P, P4 2.8C. ICH5 no hardware RAID.

See this bug for lots of ACPI info about my machine:

Just checked 2110 SMP. Still won't boot hyperthreaded on Dell PE400SC/Dimension
8300 (same motherboard) with SATA drives. This is probably an ACPI interrupt
assignment issue.

Using new A04 BIOS from Dell I can make this work with a custom
kernel. Stock kernel does not have libata SATA support built in.

Comment 4 Jeff Garzik 2004-01-12 19:35:16 UTC
So, the problem is gone now?

Comment 5 Jon Smirl 2004-06-14 18:28:28 UTC
Standard kernel-smp-2.6.6-1.427 now boots ok on SATA. I haven't tried
2.4 lately.
