[Bug 55532] ipw2200 and ACPI not playing nicely

[Greg Taylor]

Public bug reported:

Binary package hint: linux

This is a recent regression, as this wasn't happening on Dapper a while
back. The following report is based on what I'm seeing on a Canonical-
Issued Toshiba Tecra A4, which has historically had some problems with
ACPI. The most recent fix involved actually enabling ACPI, as having it
disabled caused a similar problem to this. It is possible that the
condition that disables Tecra A4 ACPI's automatically has been extended
to do so on the latest Toshiba BIOS. Previously it'd disable ACPI if it
saw you had 1.60, I upgraded to 1.70, thus making sure ACPI was enabled
at boot time and the problem was fixed.

In any case, here's the errors I get after manually removing and re-
adding the module via modprobe:
