It works in 2.6.21.5. Both kernels have: CONFIG_KEYBOARD_ATKBD=y CONFIG_SERIO_I8042=y The 2.6.21.5 kernel logs this stuff during boot: serio: i8042 KBD port at 0x60,0x64 irq 1 serio: i8042 AUX port at 0x60,0x64 irq 12 input: AT Translated Set 2 keyboard as /class/input/input0 atkbd.c: keyboard reset failed on isa0060/serio1 (The "keyboard reset failed" has always been there and the keyboard has always worked, it doesn't seem to indicate any actual problem) The 2.6.22.1 doesn't log anything like those 4 lines. The only new thing that shows up in 2.6.22.1 is console handover: boot [udbg0] -> real [tty0] Aside from those lines, there's an exact line-for-line correspondence between the boot logs. I can log in over the network while running the broken kernel, but I'm not sure what information I should be gathering once I'm in there. In my attempt to understand the workings of input/serio/i8042.c, the only result so far is that I noticed an unimportant typo in the 2.6.22 patch ("readinng" in the comment above i8042_toggle_aux).
