[issue2148] DFBSD v2.13.0.38.g09a36 - Switch to TTY panic
Antonio Huete Jimenez <tuxillo@quantumachine.net> added the comment:
>From what I've seen in the syscons code, save_kbd_state() and update_kbd_state()
are never called with the lock held.
Furthermore, in the console path functions, specifically in sccnputc() I've
found this:
scp->status &= ~SLKED;
#if 0
/* This can block, illegal in the console path */
update_kbd_state(scp, scp->status, SLKED);
#endif
