ACPI 2.17 and 2.18: some results with SMP kernel

Postby Paavo Nurminen » Thu Feb 22, 2007 16:33

My system runs without problems SMP kernel and ACPI 2.17 or 2.18 in PIC mode. APIC mode results in error (Full hardware detect):

A disk-read error occurred. Insert a system diskette ... To start after that it needs power off, power on. System is Intel P4, Matrox G450 graphics card, Adaptec U160 SCSI diks.

Could it be that snooper has problems with AICU160.ADD driver or that both ACPI and SCSI system want to use same IRQ, 9. They share IRQ 9 happily in PIC mode.

Back with version 2.16 came error message:

Internal revision 14.103a_SMP.
The system detected an internal processing error at location:

##1800:1b4e - 0003:1b4e.
60000, 2008
0886090f

Internal revision ...
The system is stopped ...

Can you go to BIOS setup and switch IRQ9 to Reserved (ISA Legacy)? To make devices go away from IRQ9.

My system has run most versions of ACPI -- including 2.16, 2.17 and 2.18 -- quite happily in conjunction with the AICU160.ADD driver -- but my SCSI adapter is using IRQ11 and always has done as far as I recall. Might this depend on which slot it's in?

It is not possible to switch individual IRQs to reserved in BIOS, only individual slots from AUTO to 5, 9, 10 or 11. Experimenting with this I came to a situation, where none of devices had IRQ9 (in working eCS 1.2). However, onboard audio (AD 1885) and AICU160.ADD both still have IRQ11. Result is same: Disk read error.

Now I think it is best to follow Alan's idea of changing SCSI card to another slot. Could pci-sniffer take some guess work off?

Alan, do you mean that you are able run ACPI and Adaptec U160 happily together in APIC mode?

Because I noticed that in the eCS 2.0 beta3/SMP/PIC system some USB devices had picked IRQ9, I disabled all USB related lines in CONFIG.SYS and added /APIC switch to ACPI.PSD. Same disk-read error. So, has to open the box ...

Yes, the Adaptec SCSI card and all the other devices I'm using are working together using the /APIC parameter. This is an Asus A8N-E motherboard with AMD dual-core CPU; it has the nVidia nForce4 chip and allows me to "reserve" specific IRQs, so I followed Paaha's suggestion to reserve 3. 5 and 7.

What I haven't been able to test is the SATA function, as I have no SATA devices.

I have now tried every one of the five pci slots. If Auto selection is on, SCSI controller picks always IRQ9. Seems to be hard coded to card some how. Windows XP/ACPI can push SCSI controller to high IRQs.

Can you change the IRQ setting for the SCSI card if you enter the SCSI BIOS configuration program? -- Ctrl-A after the POST. IIRC, mine shows IRQ11 and won't let me change it, but yours could be different.

What BIOS version does your SCSI card have? Mine is the latest, I think, but I don't recall the number.

If you put the card in a Windowzzzze machine, is there an option to change the IRQ? If so, perhaps it would "stick."
