Hi there! I download git snapshots regularly. With kernels 2.6.23-rc1-git8 through git10 the machine hung while booting the kernel, right after the message "Marking TSC unstable due to..." With -git8 I didn't know how to debug the problem, so I used the previous kernel that worked. After reading some mail lists posts, I tried passing "acpi=off" to git10, and it worked - no hang during boot. Attached is the kernel config used for 2.6.23-rc1-git10. The machine that hangs while booting the kernel is an AMD Duron 900MHz, on an aging ASUS A7V133-M mobo (VIA KT133 chipset). Curiously, another, even older machine - K6-2 450, booted 2.6.23-rc1-git8 without any problems - without the need of "acpi=off".... using only the parameters I normally pass to the kernel in order for it to work - it has some bad RAM, so I use memmap with this older machine. If more info is needed - mail me. And please Cc: me, because I am not subscribed to the list.
