Thanks very much, can you tell me the steps of reproducing this problem? On my YeeLoong laptop, 2.6.38 runs well without any problem(30 minutes now, and I think Shiwei may have used it for several hours). The kernel config I used is arch/mips/configs/lemote2f_defconfig, and please ensure the right compiler and binutils (>2.21?) are used to compile the kernel. Please make sure BFS scheduler is disabled for it is not stable. And also, please take notice of the nop problem we have mentioned in the home page[1] of linux-loongson-community project. If you know the software which is specific to your system hang, then, fix its nops at first(with the fix-nop tool from [1]). And what's the version of your PMON and EC(cat /proc/cmdline) and which external devices are you using?
