Nice work, AFAICU this should fix a few annoying issues, right?

Can you reveal some plans of upgrading 5100/5300/5350 uCode? Any
estimate would be nice to known. This month? This year?

I am not aware of any scheduled date for a new release. Are there
critical issues that you are aware of that requires a new uCode?

I noticed new bug report about firmware failure on scp (using new
firmware). I use ssh/sftp/scp a lot, so it doesn't sound nice to me.

Moreover it seems to be quite reproductable, so I'm scared of hittint
it quite often.

Probably I really should post link to bug report:

This bug was reported against 5100 series hardware and is not present in
4965. Even so, this bug was fixed in the driver and the patch has
already been pushed upstream.

Great, thanks for clarifying. It was reported on 5100, reproduced on
5300, so I was afraid also with my 4965 :)

If I may suggest something, it would be nice to keep current status in
bug report. I was waiting to see any commend about fixing driver of
resolving report by updating firmware.

I think the information you are asking for is captured in comments 16

The new ucode seems to cause fw restarts every now and then (together
with wireless-testing).

iwlagn 0000:10:00.0: Microcode SW error detected.  Restarting 0x82000000.

I couldn't figure out how to reproduce this but it happened a few times
now since I switched to the new ucode.

Should I load iwlagn with some special debug flags?

oh no ...

What is the status when such an error occurs? Can it recover on its own
or do you need to take action? What action is needed?

If your driver is compiled with CONFIG_IWLWIFI_DEBUG then you can pass a
debug flag to the module that will print a ucode event log when it
encounters a problem like this. As it will only print out the event log
when this error occurs you can safely turn this debugging on permanently
without risking a clutter of your logs. Later, if you know how to
reproduce is you can increase debugging to get more details about what
the driver is actually doing. The debug flag for _just_ the ucode event
log is 0x40000 (like "modprobe iwlagn debug=0x40000"). The 0x43fff is a
more general debug flag that helps with obtaining more information.

When you have this data - could you please submit a bug at
intellinuxwireless.org/bugzilla for us to be able to track it?

Thank you very much

It recovers automatically, no action required. Not sure if it has any
negative impact on the connection. At least I did not notice anything yet.

Will do as soon as I find a way to reproduce it.

I am also seeing frequent loss of association and firmware restarts
with the new firmware.  On occasion, I can't recover even when I
reload the driver. Admittedly, I am using an old driver right now
(2.6.29, I think).

I'm going to upgrade to 2.6.30.1 with the latest compat-wireless. I'll
file a bug if things continue as they are.

Thank you very much for getting the new firmware out!

Cheers,

John

The better restart work was added in 2.6.31 I think, so it is only in
the recent driver that you will have a smooth recovery after a failure.
You may thus be seeing the same problem as Helmut, with him running the
recent restart code.

Even if the restart code gets you up and running smoothly after a
failure, please do submit a bug report so that we can look into this.

Can I also get this with the latest compat wireless release and
2.6.30.1? I don't usually switch to a new kernel until it's been
stable for a while.

yes - compat wireless contains all the latest code, which includes this
restart work.
