Follow-up Comment #11, bug #46817 (project grub):

As I am out of ideas for the moment, here is summary of current state.

- GRUB works with HDD and CD. It hangs when accessing USB device via biosdisk.
GRUB legacy works with USB

- GRUB can access USB HDD using native drivers (boot mkrescue image from CD
and run nativedisk)

- via biosdisk GRUB hangs in grub_bios_interrupt

- it does not happen immediately. It successfully reads normal.mod and hangs
on the first disk access when loading next module (terminal.mod in this case)

- I tried to mimic GRUB legacy logic by always reading full track, it did not

- I attach dmesg from this system for reference.

(file #35965)
