yes it seems a common rule which is applied to the patches I send to
this mailing list ;)

What do you mean by "slightly updated version" ? Did you rebase them
on top the current linux-mips tree, or something ? If not, what's your
kernel version ?

Sorry I don't understand this. Do you mean:

  a) My kernel crashed, so I gave your patchset a try but it's still
     crahshing

  b) My kernel crashed, so I gave your patchset a try and it makes my
     kernel running fine.

I assume you're saying a).

Can you give a try to 2.6.23-rc2 because it includes commit
b1c65b3988c6e29ac371ab1cbbf6c4f8fb7092f8 which might fix your
issue. That would be a side effect but it gives us a hint on your
problem.

Also your .config, dmesg files are welcome.
