Hi.
Is there a patch available for the wait instruction bug in the 5kc (RTL
Revision >= 2.1)?
As a hack I changed it to nop (in r4k_wait() ), but I believe there is a
clever solution for this.
regards

It's been fixed in RTL revision >=2.3.

You can remove CPU_5KC from the case statement in check_wait in the file
arch/mips/kernel/setup.c

Is there a way to probe for this bug, for example based on the ProductId
register?
