Wolfgang, This question is getting off the initial thread topic, but we are looking for another hardware route to a xenomai compatible CAN interface. We have an LPC bus. Do you know of any MSCAN or SJA1000 or other xenomai supported devices that have LPC bus interface? We currently don't have any other devices that require a PCI or ISA bus so if we can do it through the LPC bus that would be the best hardware option instead of using the slower super-I/O parallel port dongle interface. We also don't have an SPI interface. I was looking at the MCP2515 but without SPI that seems to be out.

FYI, I remember discussions about real-time problems with the PCAN dongle: https://mail.gna.org/public/xenomai-help/2007-03/msg00185.html See also: https://mail.gna.org/public/xenomai-help/2007-03/msg00183.html Can't remember where I got that information from, maybe from PEAK PCAN support. But that user did not have the problems you reported. Maybe it's hardware related.
