Boot delay with Asahi Linux

[bumblebeeman2]

Since the latest update, booting Asahi Linux on Mac mini M2 hangs on "Booting: nvme 0" an takes quite some time to continue. You can accelerate this by pressing Enter. Occasionally, when doing nothing or when going to the boot options you even run into some kind of XHCI timeout. It definitely wasn't like this before. I even did a full reinstall of Asahi to make sure I didn't mess up anything.

This is probably an issue between u-boot's USB stack and your keyboard. Try booting without keyboard for confirmation.
Please attach the output of lsusb -vd ${idVendor}:${idProduct}. idVendor and idProduct are printed as "ID 1d6b:0002" in the lsusb output (with different numbers).

Thanks for answering. You were right, the delay is gone without the keyboard connected. Here's the output you requested:

I'd removed Arch ARM then installed Fedora Asahi. There is significant delay between timeout 0 -> boot spinning + logo stage. About 7-10 seconds? But it always works.

Problem is it hang on second stage(spinning circle + logo). Pres ESC then systemd boot output show blah ... vconsole setup failed ...cannot log in to root ... blah messages then stop. Ctrl+Alt+Del worked. Sometimes OK, sometimes fail.

By accident, I realized external keyboard matters. Without external keyboard, boot is ok. Still there is delay after timeout 0.

Do we need to set this?

usb_ignorelist

Ignore USB devices to prevent binding them to an USB device driver. This can be
used to ignore devices are for some reason undesirable or causes crashes
u-boot’s USB stack. An example for undesired behavior is the keyboard emulation
of security keys like Yubikeys. **U-boot currently supports only a single USB
keyboard device so try to probe an useful keyboard device.** The default
environment blocks Yubico devices as common devices emulating keyboards.
Devices are matched by idVendor and idProduct. The variable contains a comma
separated list of idVendor:idProduct pairs as hexadecimal numbers joined by a
colon. ‘*’ functions as a wildcard for idProduct to block all devices with the
specified idVendor.

four 1d6b:0003, 1d6b:0002 device are USB-C gender. (two per one gender) That is connected to external USB keyboard and external SSD.

How could I try to set env var usb_ignorelist for uboot?

Thanks.
