Comment 24 for bug 662288

I'll respond to #21 and #22 in parts for clarity:

Summary of my testing (once I had achieved some reliability):

Observed the failure (hang):
1. Kernel 2.6.35-25-generic (Maverick)
2. Kernel 2.6.38-999-generic (kernel-ppa version 2.6.38-999.201102240912)
3. Kernel 2.6.35-25-generic (Maverick) + compat-wireless-2.6.38-rc4-1

No failure observed ("works for me")
1. Kernel 2.6.35-25-generic (Maverick) + compat-wireless-2011-02-24
2. Kernel 2.6.38-999-generic (kernel-ppa version 2.6.38-999.201102240912) + compat-wireless-2011-02-24

So it is clear that the problem is resolved in post-2.6.38 changes.

I'm not sure where this leaves this bug:
1. I haven't logged against bugzilla.kernel.org yet as it appears to be resolved in the latest code
2. For this "ubuntu/launchpad bug" - any linux-backports-modules-compat-wireless-2.6.38 (when released) is unlikely to be a workaround, manual intervention would likely be required.

I haven't tried binary-searching compat-wireless versions to find which change contributed the fix, as I'm not sure if that would be useful for this (ubuntu) bug, and obviously not useful to kernel as it is already fixed ;)

I'll follow up to this comment with the steps I used to get things working on each version just so others finding this bug in Google will have something reliable to work from.
