From: Thomas Renninger Subject: Avoid early hang when i8042 controller is missing Patch-Mainline: no References: bnc#528811 On latest machines without i8042 controller LED control will hang when BIOS option "PORT 60/64 emulation" is enabled (which is required for specific extra storage BIOS to work). Workaround for now: Don't touch LEDs at all. --- arch/x86/kdb/kdba_io.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/arch/x86/kdb/kdba_io.c +++ b/arch/x86/kdb/kdba_io.c @@ -23,7 +23,7 @@ #include "pc_keyb.h" #ifdef CONFIG_VT_CONSOLE -#define KDB_BLINK_LED 1 +#undef KDB_BLINK_LED #else #undef KDB_BLINK_LED #endif
