Modified files:
sys/kern subr_kdb.c
Log:
Replace critical_enter() and critical_exit() in kdb_trap() with
intr_disable() and intr_restore() resp. Previously, critical
regions would have interrupts disabled, but that was changed.
Consequently, the debugger could run with interrupts enabled.
This could cause problems for the low-level console code where
received characters would trigger an interrupt that causes
the interrupt handler to read the character instead of the
cngetc() function.
