I have two machines which freeze during boot; this seems to be ACPI-related, because with acpi=off they start. The first one is the HP DC 7700; some summary can be seen on http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1081719 It hangs after a line ACPI assume root bridge[\sp_.pci0] bus is 0 The second one is a notebook; a Roda Rocky III+ RK886EX, which just shows a blank screen. As we drive many machines from the same kernel image via PXE, I tried to insert them into drivers/acpi/blacklist.c; but that doesn't help, either - the notebook hangs as before, no matter whether I set is_critical_error or not. [ I suppose I wrote the entries wrong; is there some HOWTO? I used acpidump/acpixtract/acpitbl, copied other blacklist entries, and took "OEM Table ID", "OEMID", "OEM REVISION". Help? ] Using the "ACPI debug" kernel option showed no more messages. Help, please? What can/should I do now? Regards, Phil
