Missing entries in /sys/bus/thunderbolt/devices #9

Closed nafallo closed 6 years ago

nafallo commented 6 years ago

Hi,

I have a failed flash of the controller in my fwupdmgr history, and now I never the any new entries in /sys/bus/thunderbolt/devices. There's also a message in dmesg after the thunderbolt module have been loaded (which incur a full freeze of the system for a few seconds); thunderbolt 0000:05:00.0: failed to send driver ready to ICM

Busted NVM firmware? Is there a way to force a new binary on their somewhere lower-level?

Cheers, Nafallo

Can you please try to manually force it back on using the WMI interface? Details are here: https://github.com/torvalds/linux/tree/master/Documentation/admin-guide/thunderbolt.rst

Hi Mario,

LTNS! Yeah, I've done so and it haven't helped either. I still have no device coming up. I'm on up-to-date Ubuntu 18.04 as well, so kernel 4.15. I went as far as trying to mainline kernel 4.17.2 yesterday to no avail. Is there a way to go even lower level to force a new firmware on to the controller?

That's about as low as you can go from the OS perspective. I would contact support at this point and request HW to be swapped out. :/

FWIW this could easily be from a bad type-C cable without pull up resistors frying the TBT controller or something else like that too, it's not necessarily a FW update caused issue.
