Subject: PROBLEM: Nokia 6280 + provided USB cable throws BUG's and hardlocks.
Newsgroups: gmane.linux.usb.devel
Date: Tuesday 26th September 2006 07:45:26 UTC (over 10 years ago)
Hey

Attempting to connect and use my Nokia 6280 with the supplied Nokia
USB cable (reads: 'Type: CA-53') causes the kernel to through BUG's,
and has on occasion caused a complete lock up of the system.

This is running 2.6.18, and also occurs on the 2.6.17 series, which
was what I was using when I received the phone. I have no idea about
kernels before.

Linux sara 2.6.18-ARCH #1 SMP PREEMPT Fri Sep 22 12:13:37 CEST 2006
i686 Intel(R) Pentium(R) D CPU 2.80GHz GenuineIntel GNU/Linux

Only modification to kernel is the addition of this a patch to add
jmicron IDE support, however it still occurs without this patch
applied.

If i blacklist cdc-ether and cdc-acm, I cannot reproduce the error,
and my phone works fine as a usb-storage device.

I repeated the following trials to reproduce, each on a fresh boot:
1) Plug phone onto cable, already attached to computer. dmesg shows no
recognition of the connection and it's the same as that on a clean
boot.
2) Cancel on the phone, or select it's default mode
3) dmesg show's kernel BUG. dmesg after bug is below.

If I select USB storage, the phone goes into storage mode fine,
however upon leaving the storage mode, it drops back to it's default
mode, and causes the above BUG. This seems to be the only BUG i can
continually and safely reproduce, the others issues such as hardlocks
seem random and sporadic, and have at times occured many minutes after
unplugging the phone.

Occasionally, it doesnt bug, and I experience a wide range of lockups
or problems. I gave up my debugging when, after it entering default
mode, all my app's started dying, and would not restart saying my
libc.so file was too short, however it was fine after a reboot. The
lockups are hard lockups, sysrq is completely ignored. a trace has
been output only once upon lockup, which i am attempting to get off
the phone in question.

Kernel is a stock distro kernel, which has only one patch applied, to
add support for a jmicron IDE controller, however removing this does
not make a difference. This problem occurs on two different computers:
desktop, Asus P5LD2 motherboard, 945P chipset, Pentium D. SMP kernel
laptop, Early centrino, pretty sure it's 855 chipset, Pentium M 1.4,
SMP distro kernel.

I've attempted to CC all the correct people from the maintainer's
file, sorry if i have left anyone out or added anyone extra by
accident.

Thanks for your help, id there's anything you'd like me to try or
further information you would like, dont hesitate to ask, im greatful
for anything you can do to help.

James

Below are all the mentioned things in REPORTING-BUGS. Excuse any
nvidia mentions in the proc files, nvidia was blacklisted before
booting to do the tests and was never loaded for the tests. nor was it
loaded in the dmesg below.

config is linked as I was unsure whether it was too big. it's a stock
distro config so it has nearly everythin.
