... using a reasonable default for bcr of 0x40. But you may need to
provide better values for cir, bcr and cor.

OMG, sorry that I was bothering You but You are absolutely right and with Your
statement You brought be back on track and You made my day. Thank You !!!!!!

I just took the values for cpu and bus I was using in my lincan driver and funny
enough now it's working absolutely perfect.

Module: modprobe cc770_isa irq=0xa port=0x384 indirect=1 cir=0x61 bcr=0x4A

Was just sending 50000 telegrams, perfect and no problem at all.

Thanks a lot again!!!!

This looks like a Tested-by :-)

Wolfgang, I just sent out v4. Any chance to give this patch a try? It
would be best to use a recent kernel version but I could also adapt the
patch to your kernel version, 2.6.39, I think!?

As you are using a CC770 chip, I'm especially interested in the relevant
kernel log (dmesg) and "ip -d -s link show".

Thanks,

Wolfgang.
