NetBSD kernel boot stuck at boot device

Hello,

this is my first time writing to a mailing list, so when I did something wrong please tell me!

I am writing you because I am trying to install the NetBSD install img on my Thinkpad T490. Every boot of the flashed img results in the error of the attached image. The kernel boot process is stuck there four hours. Nothing happens after the last line anymore.

```
[ 7.2381348] uhub1: device problem, disabling port 4
[ 12.7181348] uhub1: device problem, disabling port 6
[ 18.1981351] uhub1: device problem, disabling port 8
[ 23.6781350] uhub1: device problem, disabling port 10
[ 23.7081318] swwdog0: software watchdog initialized
[ 23.7381315] boot device: <unkown>
```

I tried flashing the image from multiple linux systems (mint & void) with `sudo dd if=...install.img of=/dev/sda bs=2M` and also with fsync. I synced after flashing with `sudo sync`.

I tried it with 10 different old usb sticks and 2 off the shelf/ new ones that I bought today. Every scenario resulting in the same error. After booting 1-2 times, the USB sticks get bricked with >4000 bad blocks. Resulting in not booting the kernel anymore.

So here I am, again without working USB sticks again. I wrote to the matrix channel yesterday and they asked if ACPI is enabled in the bios, but it looks like it's default enabled on the T490. There is no bios option.

Hope someone has a clue for me. I'm an OS and NetBSD newbie, so in case you need more details, please tell me what you need to help me.

Thanks for reading this and kind regards,

Lukas Rotermund
