>Description:
I am on a Acer Aspire 5633WLMi (an old laptop) and I was trying to run the installer for the NetBSD version 10.1

Steps Taken:

- Boot USB
- A text appears asking me to make a selection on what I want to do. I type '1' and the kernel starts booting.
- After a while I get the following error:

Stopped in PID 214.214 (init) at netbsd:breakpoint + 0x5: leave

What have I tried:

- Tried all USB sockets on the laptop -> no difference
- Burned the image again on USB (many times) -> no difference
- executed in boot console 'boot -2ì -> didn't work, same issue
- tried 'boot -c' and then 'disable i915krmkms' cause it was the only related suggestion found online -> didn't work

What I have not tried:

- Burning the image into another USB

I haven't done that cause I have used even recently the USB with other distros and it was totally okay.
