When accessing the SATA discs at the same time as other discs = (for example during a fsck of all file systems on the machine) it only takes = a few seconds for the SATA discs to start reporting things like this: Interrupt storm detected on "irq20: atapci4"; throttling interrupt = source ad20: FAILURE - already active DMA on this device ad20: setting up DMA failed This is on a recent kernel (2004.07.18.05.00.00), but it's been like = this ever since the kernel preemption stuff was turned on again a few weeks = ago. With preemption disabled (by editing param.h) the system seems to be = stable, but somewhat sluggish (a simple bzip2 compress operation can generate a = load average of 10+). How would I go about debugging this? Any hints would be appreciated. I = do have KDB/DDB and debug symbols compiled in, but the machine is a = production machine so I cannot afford long debugging sessions unfortunately. Attached is the dmesg.boot and kernel config file. Below are some = settings that might be interesting from other files: /etc/sysctl.conf ---------------- kern.ipc.maxsockbuf=3D524288 kern.ipc.somaxconn=3D1024 kern.maxfiles=3D16384 kern.polling.enable=3D1 kern.polling.idle_poll=3D0 kern.polling.burst_max=3D200 kern.polling.each_burst=3D25 kern.polling.poll_in_trap=3D1 net.inet.tcp.sendspace=3D262144 net.inet.tcp.recvspace=3D262144 net.inet.tcp.rfc3390=3D1 net.inet.tcp.inflight_enable=3D1 net.inet.tcp.inflight_min=3D6144 net.inet.tcp.inflight_debug=3D0 net.inet.tcp.sack.enable=3D1 net.inet.ip.intr_queue_maxlen=3D500 /boot/loader.conf ----------------- kern.ipc.nmbclusters=3D"16384" hw.apic.mixed_mode=3D0 hw.intr_storm_threshold=3D5000 /etc/make.conf -------------- CFLAGS=3D -O2 -pipe -fno-builtin COPTFLAGS=3D -O2 -pipe -fno-builtin CPUTYPE?=3Dathlon-xp /Daniel Eriksson ------=_NextPart_000_001B_01C46D3A.3DA99070 Content-Type: application/octet-stream; name="dmesg.boot" Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="dmesg.boot" Copyright (c) 1992-2004 The FreeBSD Project.=0A= Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994=0A= The Regents of the University of California.
