Hi Stephane, i thought i used the latest version you sent with the tar-ball. But having a clean version from the mailing list is always a better starting point for tests ;-) > This > version should handle restart mechanism in a (more) correct way, for both > pcan-usb/pcan-us pro adapters now. ok. > Meanwhile, I have a look to the deadlock issue in the pcmcia driver timer > function first... Yes. Just to be sure this eject problem can generally be solved i replaced the PEAK PCMCIA card with the EMS PCMCIA card in my setup, where i only get two removal notifications when pulling the card under full rx load. Just one remark upon the USB driver: I did a cangen -g0 -i can5 to flood the USB-Pro adapter with outgoing traffic. When doing an "ifconfig can5 down" i get: peak_usb 2-2:1.0: can5: Tx URB aborted (-2) ten times (what is probably the netdev queue length) So on shutdown and/or unplugging there's something to do too. Best regards, Oliver
