ipw3945: not only it periodically dies, it also BUG()s

[Pavel Machek]

Hi!

Under not-even-high load, it periodically restarts:

Feb  5 21:08:50 amd kernel: iwl3945: Microcode SW error detected.
Restarting 0x82000008.
Feb  5 21:08:52 amd kernel: iwl3945: Can't stop Rx DMA.
Feb  5 21:12:51 amd kernel: iwl3945: Microcode SW error detected.

...I've reported this before, with full debugging. Not sure if
anything happened.

Now, I got BUG() in iwl3945-base.c: 3824

                                struct iwl3945_rx_mem_buffer *rxb)
{
        struct iwl3945_rx_packet *pkt = (struct iwl3945_rx_packet
*)rxb->skb->data;
        u16 sequence = le16_to_cpu(pkt->hdr.sequence);
        int txq_id = SEQ_TO_QUEUE(sequence);
        int index = SEQ_TO_INDEX(sequence);
        int huge = sequence & SEQ_HUGE_FRAME;
        int cmd_index;
        struct iwl3945_cmd *cmd;

        /* If a Tx command is being handled and it isn't in the actual
         * command queue then there a command routing bug has been
introduced
         * in the queue management code. */
        if (txq_id != IWL_CMD_QUEUE_NUM)
                IWL_ERROR("Error wrong command queue %d command id
0x%X\n",
                          txq_id, pkt->hdr.cmd);
        BUG_ON(txq_id != IWL_CMD_QUEUE_NUM);
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here. Any ideas?

Now it decided to be original:

Feb  5 23:55:39 amd kernel: ACPI: EC: missing write data confirmation,
don't expect it any longer.
Feb  5 23:57:37 amd kernel: iwl3945: Microcode SW error detected.
Restarting 0x82000008.
Feb  5 23:57:37 amd kernel: iwl3945: TODO:  Implement Tx ABORT
REQUIRED!!!
Feb  5 23:57:39 amd kernel: iwl3945: Can't stop Rx DMA.

Could you please point me to where you have reported it before?

Which driver and kernel are you using?

I'm using the default driver present in 2.6.24-git; I did git
checkout, this is the newest commit I have from Linus:

I could reproduce it with reduced deubgging... after 2 hours or so,
and I did 2x tcpspray + ping -f.

Is it useful, or is full dump needed?

Could you please create a new bug in our bug tracking system
(www.bughost.org) to enable us to track this problem? Please include the
relevant information from the thread as well as the information you
doscovered recently.

Thank you very much

Hmmm... bugzilla says:

    * Exact steps to reproduce
    * Reproducability of bug (e.g. intermittent or 100% reproducable)
    * Did this problem not exist in previous version of the driver?
    * kernel version
    * AP brand/model
    * dmesg output at debug level 0x43fff
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
		it would be nice to specify how to do this. It is
insmod parameter, right?

    * Type of security (if any) you are using (e.g. WEP64, WEP128, WPA, WPA2, 802.1x, etc)
    * Version of firmware
    * Version of the ieee80211 module
    * Proximity to the AP

    * Before reporting any firmware errors, please be sure to read Ben
Cahill's mailing list post on how to most effectively report such
bugs. 
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
		unfortunately the link here does not work.

BTW, why not use kernel.org bugzilla? Having to create another account
is nasty...

correct. you can do this as follows:
$ insmod iwl3945 debug=0x43fff
or
$ modprobe iwl3945 debug=0x43fff

We'll try to dig out the instructions from another location and update
that link. Thanks for letting us know.

Users can report iwlwifi bugs in many locations ... their OSV's bug
tracker (which could end up being many) as well as the kernel.org
bugzilla. We focus on bugs in the bughost.org system.

iwl3945: not only it periodically dies, it also BUG()s, and oopses

I'm connected over that iwl, so filing web form is not exactly
easy. Another day, another problem, today it oopsed:

I guess I should not have tried to fix iwl3945 by rmmoding, oh
well. Kernel is reasonably recent 2.6.25-rc0.

Thanks.

One more nit:

bugzilla-daemon@bughost.org seems like normal bugzilla, where you can
hit reply button, and control it using email... but that does not
actually work.

It would be nice to fix that. (Or at least make mail appear from
noreply@bughost.org, so that it is plain to see it does not work).

It seems that iwl3945 problem is somehow linked to
GROUP_SCHED... probably iwl can not handle latencies introduced by it?
