[Bug 40849] ipw2200 frequently fails to resume from S3

[Tom Marshall]

Public bug reported:

Affects: linux-source-2.6.15 linux-image-2.6.15-20-686 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Frequently (between 10% and 50% of the time) ipw2200 will fail to operate after
resume from ACPI S3 state.  Laptop is a Thinkpad T42 2378-XXE.  I found errors regarding TX_POWER in /var/log/syslog followed by a failed module load.  After machine is awake, retrying "modprobe ipw2200" works fine.
