regression, 2.6.26-rc7, pnp: quirk_system_pci_resources()
|
|
Hi Bjorn.
I have been running with pnpacpi=off due to testing ISAPnP/PnPBIOS but
when testing some other ACPI related problem tonight I removed that and
found that unfortunately something seems to have regressed. My soundcard
driver (snd-es1968) won't load anymore on current mainline:
===
ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKC] -> GSI 10 (level,
low) -> IRQ 10
PCI: Unable to reserve I/O region #1:100[at]de00 for device 0000:00:0a.0
ACPI: PCI interrupt for device 0000:00:0a.0 disabled
ES1968 (ESS Maestro): probe of 0000:00:0a.0 failed with error -16
===
00:01 (PNP0c02) is keeping its I/O region occupied:
===
# cat /sys/bus/pnp/devices/00\:01/resources
state = active
io 0xde00-0xde03
===
Sound used to work back when I wasn't yet booting with pnpacpi=off but I
don't quite recall when I started doing that nor have I looked yet at
why quirk_system_pci_resources() isn't doing its job. I'll investigate
if you need me to but thought I'd first throw a heap of information your
way and hope you'll have a patch for me when I wake up :-/
This is vanilla mainline, 2.6.26-rc7. dmesg, dmesg with pnpacpi=off,
lspci -vv and .config attached.
