Description Łukasz Żarnowiecki 2012-07-09 14:57:40 UTC 
I have a kernel panic when shutting down the system after added module for Ralink RT61 and installed firmware (version 1.2) on gentoo linux

I can't provide the full kernel panic information:
rt61 - config +0x1dl/0x2b0 
kernel panic - not syncing: 
Fatal exception in interrupt 
Disabling non-boot CPUs

Comment 1 John W. Linville 2012-07-09 15:40:19 UTC 
You can't provide the full kernel panic information?  Can you provide the backtrace?

Have you tried this on a 3.4 or later kernel?
Comment 2 Stanislaw Gruszka 2012-07-10 07:29:01 UTC 
Panic information could be gathered using a photo camera and then you'll need to attach photo here. 

Not sure if this could be fixed on kernel newer than 3.3, but it worth to try that.
Comment 3 Łukasz Żarnowiecki 2012-07-10 12:17:33 UTC 
How to provide the backtrace?

No, I'm not tried on 3.4 kernel.

Here is the photo from camera of kernel panic:

Comment 4 Stanislaw Gruszka 2012-07-11 11:35:16 UTC 
Please run this command on your kernel sources:

objdump -d -r --prefix-addresses drivers/net/wireless/rt2x00/rt61pci.ko > rt61pci.txt

and attach rt61pci.txt file using "Add an attachment" option.

Also would be good if you could compile kernel with CONFIG_DEBUG_INFO (if not already compiled with that option) and provide output of:

gdb  drivers/net/wireless/rt2x00/rt61pci.ko
(gdb) l *(rt61pci_config + 0x1d)

You have to do this on kernel source not installation (symbols are stripped otherwise installation will have hundreds of MBs) for example:
gdb /usr/src/linux/drivers/net/wireless/rt2x00/rt61pci.ko
Comment 8 Stanislaw Gruszka 2012-07-13 12:32:41 UTC 
I think this bug happen because at 

static void rt61pci_config_lna_gain(struct rt2x00_dev *rt2x00dev,
                                    struct rt2x00lib_conf *libconf)
{
        u16 eeprom;
        short lna_gain = 0;

        if (libconf->conf->channel->band == IEEE80211_BAND_2GHZ) {
                if (test_bit(CAPABILITY_EXTERNAL_LNA_BG, &rt2x00dev->cap_flags))
                        lna_gain += 14;


libconf->conf->channel or libconf->conf is NULL. Reason of that is unknown. Unfortunately photo from comment 3 does not show top of calltrace, so is hard to tell why those values are NULL.

If you do 

iwconfig wlan0 power off 

does that workaround the problem ?
Comment 9 Łukasz Żarnowiecki 2012-07-13 12:43:37 UTC 
1. When I restarting the computer the problem not exist only when shutting down.
2. I've made object dump on module in /lib/modules

Comment 13 Stanislaw Gruszka 2012-07-21 09:52:41 UTC 
libconf->conf or libconf->conf->channel is NULL. Unfortunately this is not sufficient information to fix this bug. Begin of the calltrace is missing in photo from comment 3, so it's not possible to tell why NULL pointer is there.

Can you grab the full calltrace using serial console or netconsole ?
Comment 14 Łukasz Żarnowiecki 2012-07-21 11:03:12 UTC 
Tell me how to do this and what I need.
Comment 15 Stanislaw Gruszka 2012-07-21 16:21:26 UTC 
To use netconsole, you need to have ethernet cable connected to the network and access to second machine in the network. Some documentation is here:

http://www.kernel.org/doc/Documentation/networking/netconsole.txt
https://wiki.ubuntu.com/Kernel/Netconsole

Setup serial console is a bit more difficult, if you do not have this already done it's not wort to bother with that. If you will have troubles to setup netconsole, I'll prepare patch to make call trace shorter, so will be possible to photo all needed information.

One more thing. You did not try 3.4 or 3.5 yet, right? It worth to try them, perhaps bug is already fixed there.
Comment 16 Łukasz Żarnowiecki 2012-07-21 17:03:56 UTC 
OK, I try to do this at the end of the week.
Just like I mentioned I wanna make the kernel better, I don't need to use that card, because I've already another one.

By the way, I'm from Poland ;)

Yeah, crash gone and device works fine. Excelent!

Could you provide the same for the newer version of kernel? I suppose problem exist in 3.4 and 3.5 too.
