Hi All,
I first reported this in Fedora bugzilla, as I'm using Fedora with a Fedora
kernel (which includes recent linux-wireless git snapshots), see here for the
Fedora bugreport:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249823
Updating from the Fedora 7 test kernel to the final results in very poor
performance, and going to even newer versions of the Fedora kernel totally
breaks connectivity. Linville thought it would be best to further discuss this
here, so here I am.
I've looked at recent git commits to the prism54 / p54pci driver and have been
trying it revision by revision, eventually I've managed to pin the cause down
to 2 patches, below is a verbatim cut and paste from the bugzilla entry,
containing my analysis:
---
I've been busy researching this and I have come to the
following conclusions.
1) with the 2.6.20-2something F7-test kernel everything works fine build date
3 march, I can give you the exact revision if you want.
2) with the fc release kerkel (3194) things work, but the connection is often lost.
3) with the 2.6.23-0.49.rc1.git3.fc8, the card asociates and thats it.
Using wireless git and out of tree driver building I've found that the following
2 patches are the culprits:
Patch causing loose off connection within seconds when fully loading the link
with a local file transfer:
http://bu3sch.de/gitweb?p=wireless-dev.git;a=commitdiff;h=62ee473d67b7ae353d210b186abaadc37a642237
Only associating and nothing else:
http://bu3sch.de/gitweb?p=wireless-dev.git;a=commitdiff;h=7d59453a9dbe50dc9bab846c410e39f8d5b10c83
And then specifically the changes to prism54common.c
This is with an isl3886 cardbus card, using the p54pci driver.
----
I would be more then happy to test any changes.
Thanks & Regards,
Hans
