Hi, Have there been any changes since 970729 that could have increased interrupt latencies significantly in the SMP kernel? I'm used to a few silo overflows now and then but kernels after 970729 have seem to have increased their frequency by about a factor of ten. My hw is a tyan S1563D 2x200 with 80Mbytes of DRAM, ide and NCR scsi. Replacing wd with v1.132 and building with wd82371 for piix3 support I still see the silo problem. dave adkins
