Hi,
The reason for boot probe_keyboard hanging on my 486 is
this piece of code in beginning of function:
/* flush any noise in the buffer */
while (inb(IO_KBD + KBD_STATUS_PORT) & KBDS_BUFFER_FULL) {
delay1ms();
(void) inb(IO_KBD + KBD_DATA_PORT);
}
Apparently, there is an endless amount of noise on
my machine. Adding a retry counter to this should
fix the problem (I'm willing to test if someone
makes the change).
Ari S.
