Do you still have a custom kernel build? If you modified the kernel
config (GENERIC), please revert and retry again (though I doubt this is
the issue).

If that does not work, I have a few other ideas. It might be a timing
issue in case the keyboard controller is emulated by the BIOS. While we
have code to measure how long it takes to query the I/O port, we do not
respect the measurement and always assume it succeeds within 100ms. A
comment in the code says that in case of emulation it could be 1000x
slower :/.

I'll make a few commits and hope that they fix your issue.
