Can you modprobe acpiphp with debug=1? And send the output?

You mentioned in another mail that you echoed 1 into the various
slots' power files.
Did you do that after modprobing acpiphp with debug=1?
If so, there should be debug output when you try and turn them
on.
It produces:
acpiphp: enable_slot - physical_slot = 1
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
acpiphp: enable_slot - physical_slot = 2
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
acpiphp: enable_slot - physical_slot = 6
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
acpiphp: enable_slot - physical_slot = 7
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
Hm, so for some reason, firmware on your machine is telling us
that it doesn't think cards are present and/or enabled.
Unfortunately, I don't know why your firmware would be saying
that. We could add some more debug printks to see what firmware
thinks about your system... Or we could just wait and see what
happens after you get your hardware replaced.
New board, the exact same thing happens.
I have a card in one of the slots only this time.
Also, quick dummy check, you are trying to power on populated
slots, right? :)
Yes :-)
Can you send the output of lspci -vv? And I like the output of
lspci -vt as well... Both before and after loading acpiphp
please.
Send privately.
No difference in before and after. Odd.
If you want to poke us again after your hardware swap, please do
so. Sorry for being not so helpful. :-/
Poke :-)
One more thing I tried was pushing the power button on the slot
manually. With acpiphp, I get the same messages as above. Using pciehp,
I get the same power fault bit interrupt storm. So no difference from
using the sysfs interface or doing it on the box side, doesn't work
either way.
I'd like to confirm power fault interrupt storm, just in case.
Could you get /proc/interrupts information after power fault
problem happens and send it to me?
Thanks,
Kenji Kaneshige
