Most recent kernel where this bug did not occur: 2.6.22 Distribution: Slackware 10.2 Hardware Environment: Motherboard: Asus A7V133-M; CPU: AMD Duron 900MHz; 256MB SDRAM; latest BIOS from manufacturer site; Software Environment: Problem Description: Linux 2.6.23-rc1-git10 hangs while booting; after posting a bugreport (http://lkml.org/lkml/2007/8/2/24), Eric Sesterhenn informed me in a private mail that he had similar problems, a how they were handled (http://lkml.org/lkml/2007/7/31/435) - that solution also worked for me. My thanks to Len Brown for the advices, and Venki Pallipadi for the solution. Posting this bugreport to include the acpidump output. Steps to reproduce: Try using linux 2.6.23-rc1-git10 on Asus A7V133-M mobo with latest BIOS.

Just started linux 2.6.23-rc4 on the machine in question with kernel parameter "lapic" - works just fine!
> http://lkml.org/lkml/2007/7/31/435 This patch shipped in 2.6.23-rc3 -- so if you had the same problem, then 2.6.24-rc4 should boot correctly without any boot parameter workarounds -- can you confirm that? Note also, that if the BIOS did not enable the LAPIC by default, that is generally a very bad idea to force enabling it with "lapic". Please attach the output from dmesg -s64000 for confirmation of the successful boot and cross reference with the acpidump output.
Just started 2.6.23-rc4 without any special parameters, and yes, Len, I confirm it boots correctly. The following attachment contains the requested dmesg -s64000 output.
