Linux hangs on NVMe detection

NXP LX2160

Trying to switch back to Linux for a quick test, the board doesn’t complete the kernel boot sequence:

The drive is formatted for QNX, not Linux, but that shouldn’t matter as I don’t believe it is trying to mount anything at this point. The Debian system should be on the eMMC, per the instructions in the Getting Started guide for the Honeycomb.

Is there an option to suppress NVMe detection that can be added to the u-boot command?

you can add something like initcall_blacklist=nvme_init to your kernel command-line args

I tried adding that to the bootargs u-boot environment variable, but I think it gets ignored.

I assume that command line comes from somewhere else.

it may be hard-coded in your extlinux.conf I am not sure what Debian does for this.

Yes, there doesn’t seem to be a way to update that file without booting the system, which is a bit unfortunate.

Anyway, after a few attempts it finally booted. Not sure what changed, but it’s good enough for me.
Thanks for the help.

For the record, though, once it booted I modified /extlinux/extlinux.conf to update the command line per your suggestion. It then took effect on the next boot.
