Specifically when using an AVM Fritz! PCI card? Since I put the card into the system and enabled i4b I am seeing random crashes. The card also wedges from time to time during transmit; only closing the connection using user-mode ppp and bringing it up again unwedges the card. So far, any odd behaviour occured only while the ISDN connection was up and user-mode ppp was talking to the box on the remote end. System behaves normally when the ISDN subsystem is not in use. I have currently booted to a non-SMP kernel on the box and it is stable so far. Some more info about the system: Tandem S110 2 x Tyan S1568 mainboard, one running FreeBSD 4.1-stable (contains the card), the other one currently disabled. Running 2x200 Mhz Pentium Pro, not overclocked, ECC RAM. Also in the system are 1 Matrox Millenium, one Asus NCR875-based SCSI controller and on 8-bit parallel port ISA card. One ATAPI CDROM, one floppy. ISDN card BT Speedway ISDN, aka AVM Fritz! PCI Running 4.1-stable as of Friday, rebuilt today. Using i4b as it comes with the system (i.e. no updated to 0.95) Unfortunately I did not have any crash dumps (or kernel symbols) enabled when the box crashed so I don't have any usuable backtrace. The function name of the function that was listed as being the one it crashed in indicated that the crash occured somewhere in the SMP subsystem. I will try to reproduce the crash during the next couple of days but the system is 'production' at the moment so I cannot reboot it at will.
