I have build xeno-3.0.rc7 with kernel 3.18.12.
I have a PEAK-PCIe CAN card in my system.
Drivers are loaded and rtcan0 en rtcan1 are created in /proc/rtcan.

However, I'm not able to set the baudrate when I'm execute 'rtcanconfig rtc=
an0 -v -b 1000000 start'

By adding debug statements in rtcanconfig, I found that ioctl(can_fd, SIOCS=
CANBAUDRATE, &u.ifr); fails,

errno gives : SIOCSCANBAUDRATE(errno=3D19): No such device

Below the output of rtcan0/info and xeno-config --info

Any suggestions ?

Frederik
