Which kernel version?

interrupt problem with MPS 1.4 / not with MPS 1.1 ?

[thunder7]

Hardware:

Abit VP6 (Via 694x) x86/SMP motherboard
with USB controller

If I set the bios for MPS 1.1, USB runs fine. If I set the bios
for MPS 1.4, I get this:

May 31 13:08:06 middle kernel: hub.c: USB new device connect on bus1/1, assigned device number 4

May 31 13:08:22 middle kernel: hub.c: USB new device connect on bus1/1, assigned device number 9

Now I understand this mail doesn't have all the necessary info, but my
question is:

What information would be necessary to debug this?

dmesg
/var/log/messages
lspci -vv (or -x?)

or more?

Is the BIOS set to "Plug and Play supported OS" somewhere?  If not, try
enabling it.

Also the MPS 1.4 boot messages would be helpful :)

thanks,

2.4.5-ac4, but I rebooted in 2.4.4 and it did the same.

I'll try and add some info here (from the bios= MPS 1.1 case!)

I have the following expansion cards:

Matrox G400 agp video-card

NCR860 ultra-scsi card
Soundblaster Live! 5.1 card

I know that with MPS 1.4, the USB controller finds itself at an
unshared interrupt 19. I can't reboot at the moment to check.

Good luck,

the APIC sits in the southbridge.
the low 2 bits of offset 0x58 must be set [route USB IRQ to APIC], and 

lspci -vx -s 00:07.2

offset 0x3C must be set to 3 [19 & 15]

There was some discussion about the same problem with the sound part of
the southbridge.

What are the current values of these registers?

If an IO-APIC is present, 2.4.5 automatically routes all Via IRQs to
external APIC.

See quirk_via_ioapic in drivers/pci/quirks.c.

I have received reports that MPS1.1 works on SMP Via boards, while
MPS1.4 kills it.

It wasn't set, but with it set there is no difference.
