@Radolslaw -- I believe that the first bug above (PLCP-related) is the
one fixed by the commit below, this commit seems to be wending its way
to mainline so I would like to get some testing and confirmation that it
fixes at least one of these categories of bugs:
commit c91d01556f52255a31575be0cb1981c92a2a5028

iwl3945: remove plcp check
Patch fixes:
https://bugzilla.redhat.com/show_bug.cgi?id=654599
Many users report very low speed problem on 3945 devices,
this patch fixes problem, but only for some of them.
For unknown reason, sometimes after hw scanning, device is not able
to receive frames at high rate. Since plcp health check may request
hw scan to "reset radio", performance problem start to be observable
after update kernel to .35, where plcp check was introduced.
Bug reporter confirmed that removing plcp check fixed problem for him.

I have built some kernels with this patch applied. These are Natty
kernels but should function at least on Maverick. If those who are able
could confirm whether this fixes this issue for them. I am most
interested in those who already found that the fixes in #236, #237, and
#250 already fixed them; this is most unlikely to fix you if those did
not. If these are successful we can consider this fix for Maverick.
Please test and report back here. Kernels are at the URL below:

I will note that clearly (as Radoslaw correctly points out) at least 3
issues here. A bug really only usefully can represent one of these; in
part a launchpad limitation, part human. I am therefore nominating this
bug to represent the class of issues fixable via the PLCP fix. We will
want to split the other two known issues off to separate bugs so we can
gather only the symptom data for those specific issues.
