When I installed a mips cross compiler from Code Sorcery, I tried to compile a helloworld testcase, but I met the following errors:

Compiling with:
mips-linux-gnu-gcc -static -EL hello.c

gem5 said:
panic: Page table fault when accessing virtual address 0xffff9014

The reason is that the executable file detected the low linux kernel version of gem5, and called the __libc_fatal function.

Done.
