Not sure this will help. But please take a look at.

HI:
I'm encountered pretty much the same problem here
I'm tracing with current 3.3-rc4 branch(from ralf's tree)
If I put rootfs at nand flash + highmem enabled, then execute problem may give
illegal instruction error, bus error, try it again may run success.
but if I don't enable highmem, then problem is gone.
any hints? thanks

Hi,
I am using mips-linux-3.0.4 with HIGHMEM enabled. Everything is working fine, but I find something strange that when I execute a statically-linked binary through NFS mounted directory. It will gives me an illegal instruction error or SIGSEGV. If I run it again, the binary can run without problem. I have to reboot or drop all the vm cache in order to reproduce the error again.
Also, if I run the binary in harddisk or dynamically link the binary, no problem will be found.
Any suggestion to debug this problem? Thanks.
Jacky
