Otherwise please code a real fix, i.e. a set of buggy-R4600-specific functions, as CONFIG_CPU_R4X00 means other processors as well, e.g. R4000 or R4400 which are fine here. Actually blocking interrupts for over 0.01s as it used to be done is unacceptable, even for buggy R4600 processors. A fix should use a more fine-grained interrupt masking. Maciej -- + Maciej W.
