My hard drive is filling up with messages from peak pcan - var/log/syslog & kernel are 60-70gb and I have to delete them occassionally. They don't indicate any error, it just looks like status or "what" is happening like sending and recieving. Can I shut this off? Why is this happening? Is there really a problem pcan 7 driver, ubuntu 14.0

Ton of these in syslog:
Apr 26 16:54:49 Perception kernel: [ 122.786708] pcan: pcan_usbfd_decode_canmsg(): rx=[flags=0x00 len=0x08 ts32=0x0742ee39 id=0x0000052f]


Don't have a sample of kernel log, but it's spammed too.


Thanks,

Hi,

please send the output of cat /proc/pcan to see which driver version you use at the moment.

When using an older driver 7.x, please update to version 8.x:

Has this issue been resolved?

https://www.peak-system.com/forum/viewt ... slog#p4922 suggest turning off ACPI in BIOS.

I have the same issue and while rotating logs is one solution, it's not a definite solution. I tried upgrading the driver but my 3rd party application does not work with new driver so I'm sticking with 7.15.2 on Ubuntu 16.04.

Hi,

to prevent those syslog messages with driver 7.15.2, please edit pcan_usbfd.c line 742:

from: #if 1//def DEBUG
to: #ifdef DEBUG

rebuild and reload the driver again, and those messages will no longer occure.

best regards

Michael
