{swapper:1] illegal instruction at ...

[atul srivastava]

Hello,
I have just now enabled the nfs mount of root file system.
after this when I boot i get so many repeated messages like..

[swapper:1] Illegal instruction d0c62bd0 at 800f7c6c ra=
800f4860
[swapper:1] Illegal instruction 0031c78 at 800f5b5c at 
ra=8002d954
......
and similar many illegal instructions at different addresses.

in System.map if i watch for these adreses they are mostly from 
routines in linux/net/* and linux/net/ipv4/* directories.

what are the chances for it be compiler problem.

version of mips-linux-gcc complier that i get from
"mips-linux-gcc -v" is
gcc version egcs-2.91.66 19990314 (egcs-1.1.2 release)

can somebody suggest me something..

Best Regards,
Atul

As it seems your problem has something to do with the swapper, are you 
also trying to swap over nfs ? I think you need patches for that:

Just a few items to check:

 - memory hw problem
 - memory controller configuration
 - caches not properly flushed
 - memory corruption

Those patches are broken.  If you're using those patches, don't even
expect to dream about things working ...
