Hi,
to find my PCI problem I want to use git to find the last working
version.
I just start with head and found a compile error:
arch/mips/alchemy/common/time.c:93: error: incompatible types in
initialization
I comment this line ".cpumask        = CPU_MASK_ALL,"
and build again.
This is the result. Somethig is wrong with the timer ...
