There have been no problems until we received recent hardware. With the latest hardware, which the vendor claims hasn't changed, the machines panic when either a USB mouse or USB keyboard are plugged in. Machine: Supermicro H8DME-2 Two quad-Core AMD Opteron CPUs 64GB DDR2 400 SDRAM 6 SATA2 3.0Gb/s HD Support 2 64-bit 133/100 MHz PCI-X 2 64=bit 100MHz PCI-X ATI ES1000 Graphics Chipset nVida MCP55 Pro NEC uPD720400 USB FUCI, uses ohci_hcd driver. When mouse or keyboard is inserted, I get a panic with: "map_single bounce buffer is not DMA'ble." This comes from: linux-2.6.11-prep/arch/ia64/lib/swiotlb.c, line 440. I added 64-bit long print hex to the panic statement so I could display the address it doesn't like. The address it doesn't like is: 0x000000022a0aa000 Does anybody have a clue what might be the matter and how to fix it?
