Bug#526763: conky: freezing system or segmentation fault on 2.6.26 kernel together with orinoco_usb rev. 1300

thanks

Hello,

The original submitter was unable to reproduce the bug. Moreover, the
bug appeared to be with the kernel module used by the submitter
rather than with conky.

In case this bug is not reproducible by anyone over the next 60 days,
I will close it.

Regards,

Kapil.

Bug#526763: conky: freezing system or segmentation fault on 2.6.26 kernel together with orinoco_usb rev. 1300

2009-05-03 Thread tangwart
Package: conky
Version: 1.6.0-2
Severity: important

Hello all,

Conky seems to conflict with the orinoco_usb driver of my wireless 
network card. It's an Orinoco usb device that works with the Linux 
orinoco Driver from http://sourceforge.net/projects/orinoco/

The system freeze, so that you have to use the reset-button, or in some 
less times it continues with segmentation faults.

I can't produce the error. It just happen after some seconds or minutes 
when conky is running and the orinoco card is
switched on. 

I used the rev. 1300 of orinoco_usb

I also report the problem on the orinoco-users mailing list 
[http://sourceforge.net/mailarchive/forum.php?forum_name=orinoco-users].

With the older kernel 2.6.18 and the rev. 1273 of orinoco_usb I could 
avoid the problem.

Regards.

P.S.: Here is what said dmesg, when the error happend without freezing 
the whole computer:

Since conky is a userspace program it seems unlikely that the bug
is here. It is most likely with the orinoco_usb driver that you are
using.

 I can't produce the error. It just happen after some seconds or minutes 
 when conky is running and the orinoco card is
 switched on. 

This makes it even more difficult for anyone else to reproduce the
bug.

 I used the rev. 1300 of orinoco_usb

Which presumably means that you are using a self-compiled driver
rather than a driver that is distributed by Debian. This means that
you should report your bug at the web-site of the orinoco driver as I
see that you have already done.

In principle, you could hack conky to ignore your device but that
would be rather pointless since some other userspace program may then
trigger the bug in the driver you are using.

Regards,

Kapil.

P.S. In case you *are* using the orinoco driver from the Debian
kernel, please reassign the bug to the appropriate kernel package.
