Miles, Please apply the latest acpi patch directly on top of Linus' tree. http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/test/2.6.21/acpi-test-20070126-2.6.21-rc5.diff.gz If Andrew and I are in sync, you should get the same issues above as above -- no hang, but still problems 1-4. Then revert that patch and edit it to delete all changes to ec.c and apply it again. ie. keep drivers/acpi/ec.c from Linus's tree and re-test. If the symptoms 1-4 go away, then we've isolated the regression to the changes to ec.c. Also, it might be helpful to open up a bug report here: http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI and attach to it the output from acpidump thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
