Hi!
I have been unable to boot kernels since 2.3.33, I always get
about 1000 "pc_keyb: controller jammed (0xFF)." messages
and then a
NMI Watchdog detected LOCKUP on CPU0, registers:
(see below)
console shuts up ...
And now nothing much happens, I had a working 2.3.25 kernel but did not
try all the kernels in between so I dont know if this is the exact
place for the introduction of this behavior. But I do have a suspect:
http://www.kernelnotes.org/v23patch/patch-2.3.33/linux_drivers_char_pc_keyb.c.html
I have not seen any references to this problem so I decided to try my
luck here. I must admitt that I have not done any kernel hacking yet
but I believe that this problem might affect others, so it should get
reported.
I downgraded my gcc to 2.7.2.3 and tried different kernels, with no
succcess. I even tried two keyboards. And the last thing was to
download a fresh copy of the kernel.
My machine is a dual Pentium II 266 Mhz Supermicro 6DSL MB
