Apologies for the noise. I'll check the Ubuntu patches. Thanks for your time.

This patch, and by consequence the bugreport is to ubuntu-specific code, not upstream GRUB. So you report it to the wrong place.

My quick test has showed that GRUB doesn't touch numlook setting. And there is no code to do so other than in sendkey module. Linux, on the other hand has cleared numlock. So this bugreport is likely misplaced. Observations were done with looking at LED. Bit 1 in 497 is only about keyboard LED status, not about keyboard status which is saved in 0x417.

For BIOS versions that support "Numlock on boot" 0x497 bit 1 will be set, indicating the numlock is set.

As soon as GRUB loads, this bit is cleared.

This is a regression from 1.97
