I'm not sure which. :-) I have 3 machines with ACPI BIOS here, I have no serious problems with ACPICA code luckly (or unfortunately? :-) However It seems that there are some bugs in ACPI CA code, acpi-jp folks and some developers from Intel are discussing this sometimes at acpi-jp@jp.freebsd.org. The problem you are having is reported by VAIO Z505JX user; some ACPI methods seems cause infinite loop within the method. Unfortunately we haven't find the effective solutions for it. Could you disable dev/acpica/acpi_*.c lines in sys/conf/files and see which module cause this hang? Oh yes, and please dump your Z505JE's DSDT data with `acpidump -o' and send it for us. This would be useful for debugging. > Those paying attention on -hackers know I've offered a prize for a > jogdial driver.
