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 ;-)

ok.

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
