with the latest cvsup'ed, the em is sending packets but not receiving. the last working version that i have is from 3rd. Oct. host is S2466 TIGER MPX, but have seen the problem on PIII/STL2. o- there is no if_em changes that i can see. o- smp/up has no effect - the kernel is smp, just fiddling with kern.smp.disabled o- there is no usb, nor shared interrups that i can see. cheers, danny
