AR5424 diffirent errors before and after recompiling same kernel

sergey.kish
My Acer Aspire One 751 shipped with Atheros AR5424.
It isn't supported, but was found during boot

> ath0 at pci2 dev 0 function 0 "Atheros AR5424" rev 0x01: apic 2 int 17 (irq 4)
> ath0: AR5424 14.2 phy 7.0 rf 0.0, WOR5_ETSIC, address 00:24:2c:6f:ab:c0

It fails to scan network:

        $ ifconfig ath0 scan debug
        ath0: unable to reset hardware: hal status 3

I've found that Luis Henriques was able to use it year ago
http://www.mail-archive.com/tech@.../msg01613.html

So I've started from recompiling my kernel.
No changes applied just src.tar.gz by ftp and recompiled kernel

Running same command gives me other errors:

        $ ifconfig ath0 scan debug
        ath0: unable to reset hardware; hal status 200
        ath0: unable to reset hardware; hal status 3692322168

Running again gives only second:

        $ ifconfig ath0 scan debug
        ath0: unable to reset hardware; hal status 3692322168

Why? I've made no changes in kernel and I was waiting for same error (status 3)!

there was no changes except recompiling kernel. I've downloaded src.tar.gz and sys.tar.gz from ftp://ftp.spline.de/pub/OpenBSD/4.8/

which is official ftp mirror
12:33 < sergeykish> then I've used instructions from http://openbsd.org/faq/faq5.html 5.3.4 - Building the kernel

12:36 < sergeykish> yes, AR5424 isn't supported, but I've found http://www.mail-archive.com/tech@.../msg01613.html
12:36 < sergeykish> and first step is recompiling kernel and checking same behaviour
12:37 < sergeykish> but for some reason it is changed, why?
12:37 < sergeykish> (I've recompiled kernel without patch)

Short answer, it doesn't work.

As you can see I've already red it. But here I'm not asking how to make AR5424
work. My point is different.

I've made no changes and wait for no changes.
But behaviour changed!

        -ath0: unable to reset hardware: hal status 3
        +ath0: unable to reset hardware; hal status 200
        +ath0: unable to reset hardware; hal status 3692322168

Why? Does install binaries were made not from provided source?

No, that is for an AR5424 10.2 phy 6.1, this will
not work with your AR5424 14.2 phy 7.0

> Why? I've made no changes in kernel and I was waiting for same error (status 3)!

Possibly the card is in a different state (cold boot vs warm boot)?
Could be lots of possible reasons.

I would suggest one of the mini-USB devices (or swapping the internal
card, but the mini-USB ones are much cheaper+easier to buy).

No, same state. I've copied binary kernel "bsd" from mirror and it
returns error 3 again.
What's why I've posted here.

No dmesg, don't state what kernel you downloaded (snapshot?  4.8?),
and don't state what source branch you built from.  You didn't read
the "How to create a problem report" section of the FAQ I guess.

To head off a question: SNAPSHOTS OFTEN CONTAIN CODE THAT HASN'T BEEN
COMMITTED.  Similarly, there are often commits between when a snapshot
build started and when it was posted.  Failing to include dmesg output
means you don't really want an answer.

First, why do you not think you have an AR5424 chipset? I ask because
you've said so elsewhere.

> ath0: unable to reset hardware; hal status 200
> ath0: unable to reset hardware; hal status 3692322188

Second, I wonder if you have that card marked as 'up after the
recompile. I have the same card and when I have it marked as 'down'
there is no problem. In fact, I wonder if compiling the kernal has
anything to do with it, because I've done that too with no "unable to
reset hardware" mesage. that message only occurs when I  mark the card
'up' and try to use it.

So, to "fix" the issue (if it is what I think it is), mark your card
as 'down' (i.e., ifconfig ath0 down). It's not supported (yet),
anyway.

It is not AR5424.
My question is simple "Why is it different?", maybe
"What else can be different?"

No, my issue isn't few lines in dmesg then
I try to use hardware. But working hardware.

Sorry, got confused by your dmesg, the subject to this thread, and the
subject of the message you sent to dmesg@ . . .

You want to know why those lines are added to your dmesg, no? You want
to know what "the difference" is. I'm suggesting that, after you did
something (not necessarily the kernel compile), "the difference" is
that your system is now trying to use a card that is unsupported.
