Subject: Kernel Panic: DM9601 Fast Ethernet Adapter on ARMv7
Dear list,
Peter as the maintainer from MAINTAINERS is not reachable by mail
(mail delivery failed) so I send this to the list directly.
I am experiencing a kernel oops on a regular basis with a DM9601 Fast
Ethernet Adapter on an Raspberry Pi 2 Model B.
I collected as much information as possible accordingly to
https://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html
I already reported the bug here
https://github.com/raspberrypi/linux/issues/1045
It was mentioned that it is known that the driver is broken.
Can and will you fix the driver? Any help is appreciated.
Best regards
Dave
[1.] One line summary of the problem: Kernel Panic: DM9601 Fast Ethernet Adapter
[2.] Full description of the problem/report:
Kernel on Raspberry Pi 2 oopses when some significant traffic occurrs.
Pinging sometimes works fine, but downloading a file oopses the kernel.
[3.] Keywords (i.e., modules, networking, kernel):
[4.] Kernel version (from /proc/version):
pi@...pberrypi:~$ cat /proc/version
Linux version 4.1.10-v7+ (dc4@...-XPS13-9333) (gcc version 4.8.3
20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC
2014.03) ) #821 SMP PREEMPT Sat Oct 10 00:16:28 BST 2015
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
See end of report.
[6.] A small shell script or example program which triggers the
problem (if possible)
wget http://cachefly.cachefly.net/100mb.test
Will certainly oops.
