If I unplug the DVD drive the problem naturally disappears. The machine is an Intel SR1530SH.

MGA G200e [Pilot] ServerEngines (SEP1) (rev 02) 04:02.0 Ethernet controller: Intel Corporation 82541GI Gigabit Ethernet Controller (rev 05) I've tried switching acpi off, using irqpoll, switching from AHCI to RAID in the BIOS but it makes no difference at all. I also tried kernel 2.6.21.5 (Slackware 12.0) and the problem is still there. Any ideas? Thanks Paul
