Hi Pavel, we already changed the BUG_ON() to WARN_ONCE() in Linux Mainline: http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=commitdiff;h=1758c0947605211ef953cc91d6bbdf847a21b822 You may apply the patch to your Kernel also. > > At the same moment there is no testing can_dlc for values > 8 in > sja1000_rx (sja1000.c) > > Could you suggest something? A can_dlc > 8 is always a bug and should never happen. I'll fix that in the sja1000 driver. Thanks for the hint!
