Comment (by siarzhuk):
The possible suspect is ps2 controller throwing no interrupts on key press
or issuing wrong interrupt state.
May I ask you for another test with just attached ps2 bus manager? This
customized manager has additional check of ps2 controller command byte and
tries to re-enable keyboard interrupt in the command byte on keyboard
opening. It also produce some tracing for interrupts with OBF bit unset -
probably they where ignored silently. Please use listed above procedure to
perform this test. Note that it would be nice if you press any keys more
that 30 - 50 times. It helps me to see if the keyboard interrupts were
issued or not.
Another possible point to test is checking KDL's "ints" state. Please try
to press simultaneously Alt-Print-D keys. In case you fall through into
Kernel Debugging Land successfully please check the following:
1) run "ints" command. note the count of handled/unhandled interrupts for
"int 1";
2) run "es" command to go out of KDL;
3) press any key about 20 times;
4) press Alt-Print-D to go into KDL again;
5) run "ints" command and note the count of handled/unhandled interrupts
for "int 1" and show me, please, those counts from step 1 and step 5 in
comparison.
Please do not disappoint in case you cannot go into KDL by Alt-Print-D -
it is predicted behavior for non-working ps2 controller. ;-) But you have
said in the problem description that you can use keyboard in "debug mode"
- did you mean KDL?
Thank you for assistance and please exuse me for some delay. Good luck!
