Andrew, 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, for example, 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.
