Cyrus, original message: >>But there is a problem that occurs while I stream in lots of data from an >>SMC 100mbit ethernet card while the cpu's are busy.

If your goal is just a stable SMP then you need to use -current as of the date of last sync: Peter says: >Also, the SMP kernel was synchronised last to the 9-Feb kernel, right >before the import.
