When trying to boot Fedora's 3.10-rc2 build on my old P4 based laptop (sis chipset) it gets stuck right after the following line: ACPI: Added _OSI(Processor Aggregator Device) When booting Linux-3.9.3, the line which appears after this is: ACPI: EC: Look up EC in DSDT Please see the screenshot, lspci output as well as a dmesg output of kernel-3.9.3 attached.

Please provide the output of acpidump and do bisect to find which commit cause this regression.
BTW, please try latest upstream kernel(v3.10-rc2) to confirm whether the issue exists in upstream kernel.
Unfortunately I don't have the time to bisect this issue. However I'll provide an acpidump soon.
Currently, there is no way to judge how the issue happens and the log in comment #1 is too limit. So bisect is the best to find the cause.
How about with "acpi=off" kernel parameter?
There is no more clue because it just gets stuck during bootup and bisect is the best way to debug now. From comment #6, you have no time to do bisect no. So mark this bug close as WILL_FIX_LATER. If you have time to do bisect, please feel free to reopen this bug. Sorry.
