Description

Hi, I've faced a problem with couple of latest images for my rspro.
I've tried to install couple of images and seems like the trunk and altitude_adjustment images have major problem.
Judging from this:

...
[   12.340000] usb 1-2: new high-speed USB device number 2 using ehci-platform
[   14.200000] device eth1 entered promiscuous mode
[   14.720000] eth0: link up (100Mbps/Full duplex)
[   15.720000] eth1: link up (1000Mbps/Full duplex)
[   15.730000] br-lan: port 1(eth1) entered forwarding state
[   15.730000] br-lan: port 1(eth1) entered forwarding state
[   17.730000] br-lan: port 1(eth1) entered forwarding state
[   27.740000] eth1: link up (10Mbps/Half duplex)
[   29.750000] eth1: link up (1000Mbps/Full duplex)
[   47.760000] eth1: link up (10Mbps/Half duplex)
[   85.130000] Kernel bug detected[#1]:
[   85.130000] Cpu 0
[   85.130000] $ 0   : 00000000 80330000 ba000000 00000000
[   85.130000] $ 4   : 0000000a 00000001 00000001 00000000
[   85.130000] $ 8   : 879b5fe0 0000fc00 00000000 802d6000
...

the problem is related with with AR8316 switch on rspro.
Unfortunately google did not helped me and i've decided to open a ticket.
Attached You can find full output with lots of debug jazz from version 12.09 which is way out of my knowledge.
I was able to figure out is that:
Image: http://downloads.openwrt.org/backfire/10.03.1/ar71xx/openwrt-ar71xx-ubnt-rspro-squashfs-factory.bin
is OK
Image: http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-ubnt-rspro-jffs2-factory.bin is affected
Image: http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-ubnt-rspro-squashfs-factory.bin is affected
Unfortunately I have no clue when exactly this problem rizes.

Hello nbd,
have you been able by any chance to have a look at my problem?
Thanks, and sorry to disturb.

No, but please try a newer version anyway. Another developer committed a fix that might be related to this issue (r38689)

Thanks for reply!
Unfortunately no changes for me... build from 16-Nov-2013 11:37 behave just the same way.

also problem. dir-615 e4

comment:7 Changed 4 years ago by anonymous

I don't think that problems with these two devices are related, CPU is different, switch is different.

Hi,
I wonder if i am the only one who faced such behaviour?
