This entry is being used for tracking a regression from 2.6.28. Please don't
close it until the problem is fixed in the mainline.
Will you please attach the output of acpidump?

please help to locate which line code causes the crash.
Build kernel with CONFIG_DEBUG_INFO=y, as below
menuconfig->General Setup->Optimize for size, disable this option
menuconfig->Kernel hacking->Compile the kernel with debug info, enable this option
reboot with this new kernel, then check EIP that causes the crash,
EIP: 0060:[<c0441898>] EFLAGS: 00010217 CPU: 1
run addr2line to get the line of code,
addr2line c0441898 -e vmlinux
This problem appears to have been resolved in 2.6.29-rc4. I have now built a kernel 2.6.29-rc4 with exactly the same configuration as earlier and it now boots and runs without this problem.
good news. close this bug.
please re-open it if it can be reproduced in the upstream kernel again.
