Ultimately, you should have CONFIG_ACPI=y and CONFIG_PNPACPI=y, and you should not have to boot with "noisapnp" or "pnpacpi=off". My guess is that you only need "pnpacpi=off" to work around the current problem. At http://linux.lang.hm/linux, I see dmesg logs (with tons of kobject debug that's useless to me) from 2.6.22-rc4. It would be useful to have the log from 2.6.22-rc4 with "pnpacpi=off" (which I expect to work), so we could compare it with the "2.6.22-rc4.dmesg" log, which I assume a non-working one. Linux PNPACPI currently doesn't manage resources quite the same way Windows does, and that might account for this problem. You might try this: - boot without "pnpacpi=off" (leave PNPACPI enabled) - before loading the parport_pc driver, do this: # echo "disable" > /sys/devices/pnp0/00:0a/resources # echo "enable" > /sys/devices/pnp0/00:0a/resources - load the parport_pc driver That should cause PNPACPI to run _PRS and _SRS. Many BIOSes report that devices are enabled, but don't actually enable them until _SRS is called.
