I just wanted to be sure, that there are no patches missing. > I'll be away next week, but after that I can at least > continue testing and maybe write some code ;-) Can you please copy | https://github.com/linux-can/can-utils/tree/master/mcp251xfd/99-devcoredump.rules to "/etc/udev/rules.d" and | https://github.com/linux-can/can-utils/blob/master/mcp251xfd/devcoredump to "/usr/sbin" If the IRQ handler fails with an error, the driver will generate a dump of the driver and chip state and write it to "/var/log/devcoredump-*.dump". Please send me this file. Please use the unmodified v6.11 version of the driver on your v6.6 kernel. regards, Marc -- Pengutronix e.K. | Marc Kleine-Budde | Embedded Linux | https://www.pengutronix.de | Vertretung Nürnberg | Phone: +49-5121-206917-129 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-9 |
