Information about the problem of non-recognized 3Com Ethernet card when using ACPI with 2.6 kernels.

Problem description

When using a 2.6 kernel with ACPI enabled, the card is not recognized properly. In fact the kernel finds the card and tries to enable it but gives an error message in dmesg output.

Affected Models

Affected Operating Systems

  • all Linux flavours


This is a problem of the ACPI subsystem interfering with the PCI resource management.


Try one of the following kernel parameters (in that order):

  • nolapic (disables support for local apic)
  • acpi=nopci (disables PCI resource control of the ACPI subsystem)
  • acpi=off (completely disables ACPI, should always work)
