> Why is pci=noacpi being used?
My system booted for kernels <= v2.6.15 either with "acpi=off" or
"noapic" or "pci=noacpi". Boot option "noapic" made problems with
suspend-to-RAM, so I took "pci=noacpi". Now, I after much testing those
problems turned out to be a simple missconfiguration of acpid's
button/power event handler:
When booting in IOAPIC mode either together with pci=nacpi or or not I
did *not* get right after transition from suspend-to-RAM to
On-power-state a "button/power" event. So I had no problem with the
simple button/power-handler
[EMAIL PROTECTED]:~$ cat /etc/acpi/actions/my_powerbtn.sh
#!/bin/sh
echo mem > /sys/power/state
But with "noapic" no matter if I have "pci=noacpi" or not I *do* get a
"button/power" event right after resuming from supend-to-ram (by
touching my powerbutton) and so my system got back in S3-State...
No I use the improved better handler
[EMAIL PROTECTED]:~$ cat /etc/acpi/actions/my_powerbtn.sh
#!/bin/sh
# suspend to mem (S3, "mem") on button/power acpi event
POWERBTN="/var/run/powerbtn.eid"
suspend_to_mem() {
echo $eid > $POWERBTN
echo mem > /sys/power/state
}
# event arguments "%e" look like
# button/power PWRF 00000080 0000002e
eid=$(printf "%u\n" 0x${4}) # simple hexadecimal to integer conversion
if [ -f "$POWERBTN" ]
then
# catch and ignore button/power event on transition to power-on state
read oeid < "$POWERBTN"
if [ $(($eid - $oeid )) -ne 1 ]; then
suspend_to_mem
fi
else
suspend_to_mem
fi
and all works fine with noapic.

You are right. System boots. Interrupt increases. button/power and
button/lid events are all right. So no problem with EC for me any more.
Thank you very much!!!
But my system now works just with option "noapic" fine and video-console
resumes better with "acpi_sleep=s3_bios". So I do not use ec_intr=0 or
pci=noacpi any more. I think in general it' s better to use ACPI for IRQ
routing, yes?
I think this bug is resolved? But better you will decide that. Any chance
that users won't have to experiment with incomprehensible boot options in
the future?
