Description:The system will suddenly stop responding to all user input. No mouse, keyboard response and no call processing. This occurs infrequently but about 2/3 times a day on average.

Looking at the messages log before each reboot (shown in the included file) led me to believe that this was due to a problem unloading calls from the ISDN connection (mISDN).
These are the problems reported;
 HFC-S USB: CRC or minlen ERROR
 channel_senddata: next_skb exist ERROR (skb->len=64 next_skb->len=64)
though these aren't always present, on other occasions the last line recoreded before reboot is;
 release instance class dev inst-50010201


Originally the system was built on the 19th of Feb. This would mean that the SVN of mISDN was the 16th Feb version, however, I recomplied the channel drivers (including misdn) lastnight (12noon GMT on the 1st of March).

This issue has persisted.

I'd like you to post that issue on the mISDN bugtracker at:


since the developers of the hfcsusb driver are reading this bugtracker only i think.

Do you get a Kernel Oops? Can you make a digital photo of it and attach it to the bugreport please.

chan_misdn cannot cause the system to freeze. It is only a userspace programm. It is mISDN which freezes the system.
