May be it is running out of space for per cpu area. You can try by increasing the PERCPU_ENOUGH_ROOM in include/linux/percpu.h and see if get pass. I looked other 64 bit archs x86_64 and ia64 and they both have different value. May be alpha also needs a different value. -aneesh -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
