As you likely already know, this is a kernel / BIOS issue, not a 3Com driver issue.

(It's more likely to be an issue on a desktop with a PCI-CardBus adapter.) > Oct 24 19:11:40 debianlap kernel: Linux Kernel Card Services 3.1.22 > Oct 24 19:11:40 debianlap kernel: options: [pci] [cardbus] [pm] > Oct 24 19:11:40 debianlap kernel: PCI: No IRQ known for interrupt pin A > of device 01:02.0. > Oct 24 19:11:40 debianlap kernel: PCI: No IRQ known for interrupt pin B > of device 01:02.1.
