I lose all network connectivity to the machine, and I simultaneously see a DMA error occur for my primary IDE drive. Two interfaces: Quote: eth0 (rtl8168 (using rtl8169 driver) - Onboard PCI-E Gigabit Ethernet) eth1 (rtl8169 (using rtl8169 driver) - RTL8169 PCI Gigabit Ethernet) The chipset running the IDE drive that experiences the DMA crash is: Quote: ATI Technologies Inc SB700/SB800 IDE Controller (atiixp) Vitals: Debian 5.0.1 @ Kernel 2.6.30 00:00.0 Host bridge: Advanced Micro Devices [AMD] RS780 Host Bridge 00:01.0 PCI bridge: ASUSTeK Computer Inc.

Also feel free to point me in the direction of a better place to post this issue. HELP! I want to be able to multihome but this is stopping me :(
