coreboots board status repository has some
SeaBIOS warnings, and I
believe the keyboard doesn’t work in that case.
$ git grep 'Timeout at i8042_flush' origin/master --
- Timeout at i8042_flush:71!
I don't think that warning is a problem - it generally indicates that
a ps2 port isn't present. So, I suspect most of these boards lack the
I also experience this sometimes on a Lenovo X60,
when I load the
SeaBIOS ELF file from GRUB with the commands below.
> chainloader (cbfsdisk)/img/seabios
Every time, the keyboard doesn’t work – on the Lenovo X60 it’s
connected over the PS/2 port – the error message `Timeout at
i8042_flush:71!` can be seen.
Note, that it’s unlikely to be a timing issue, as the keyboard works in
the GRUB payload *before*.
Any idea, what causes the problem, and is there a way to fix it?
I don't have much help. The message appears after 16 bytes are read
from the port and the port still indcates data is available. I can't
think of any valid situation where that would occur.
Is the problem reproducible?
I couldn’t reproduce the log message above. I think, I rebuild SeaBIOS
with higher debug level, but I am not sure.
With that, I get a non-working keyboard in SeaBIOS, when loading
SeaBIOS without timeout from GRUB. Then the problem can be reproduced
each time despite having the file `etc/ps2-keyboard-spinup` with 3
seconds in CBFS.
i8042 self test failed (got fa not 0x55)
Could it be that the keyboard is in an „unclean“ state from GRUB, which
also still probed it?
