When I run the ia32 port of HelenOS mainline on my workstation Kvadrat (AMD Phenom II X4 905e Quad-Core, socket AM3 (Deneb), I am getting a 'cpu<n>: spurious interrupt (inum=1)' message upon each keyboard interrupt (i.e. each time I press or release a key).

Screenshot is attached.

Can we get this retested, please?

I am still getting 'spurious interrupt' on every keypress, but only if the system does not boot all the way to desktop. So if the boot process stops with just kernel console available, I am getting the messages. If I boot all the way to desktop, then go to kcon, I am not getting any spurious interrupt messages.

Also, USB does not work for me and I cannot receive any frames with the rtl8169 driver (although I can send frames). These issues could potentially be related to interrupt handling, too.
