From: Ole J. Hagen [mailto:[email protected]] I just wanted to inform that kernel-2.5.55 failes to boot when ACPI support is
compiled in the kernel.I have following configuration; Dell Optiplex GX-240, Pentium 4 (1.5 GHz), ATI RAGE 128.
How exactly does it fail?
My brand new Dell Latitude C640 oopses on boot in 2.5.56 if I
haveCPU_FREQconfig'd in. ACPI withoutCPU_FREQis okay - well, it screws my framebuffer screen (what 2.4.21-pre3 doesn't) when the ACPI code does its bootup printk's, but after that the screen recovers.

Back on topic, if you're interested I can rebuild my 2.5.56 with
CPU_FREQand write down the backtrace of the oops.Would be great if you could do that - and tell what oops it is (NULL pointer dereference etc.), in case you still see that on your screen.
Sigh :(
Rebuilt with CPU_FREQ, doesn't oops. It says
cpufreq: Intel(R) SpeedStep(TM) for this processor not (yet) available
Is the above message expected ? The CPU is a 1.8Ghz mobile P4.
Still puzzled as to why... wait, this was a cold boot, let me try
warmbooting... argh - the disk powered off. Bug 119 :(
Nope, coldbooted in 2.4.21-pre3, rebooted in 2.5.56, still had no
oops with a CPU_FREQ enabled kernel.

2.5.56, you say... let me check... yep, then this patch is missing (it's in 2.5.56-bk). Could you send me a /proc/cpuinfo, please? Especially if this patch doesn't work :)
