- *** 0.99pl1 has not changed my keyboard lockups for the better, it got WORSE ***
- --------------------------------------------------------------------------------
-
- Bug Description:
- ----------------
- As i posted here in this group earlier, my keyboard goes dead everytime i press
- one of the lock keys (CAPS LOCK and SCROLL LOCK led will light up, NUM LOCK led
- will go dark). But i was able to switch the vc's with no problems.
- After applying the patch1 to the kernel, i can not switch vc's any more, kbd will
- lock after the switch.
-
- What I tried to fix it:
- -----------------------
- My first suspition was that kb_wait() and kb_ack() are not working for me the way
- they should. So i added a printk(...) to show me wether the end of the for loop
- is reached without an acknoledge of the kbd-controller.
-
- Result: No message was printed, the keyboard just locked.
-
- So i digged deeper in keyboard.c and found ... nothing, except a lack of checks
- for the keyboard errors OVERRUN and RESEND. (Never thought that might be
- necessary!). So i looked through my archive and found an article in c't 6/1988
- about PC/AT/MF2-keyboards and programming the keyboard controller. Now I started
- to add more checks on the communication between keyboard and controller,
- controller selftest and some sort of watchdog which will reset the keyboard and
- the controller ...
- But since i started just yesterday i have no results. Any help or suggestions
- are welcome! (Please help me! I have started coding in C just 8 weeks ago !!!)
-
- Happy New Year!
