From 06fa46a2fcb7e13386707a3eac74f11140a9f818 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Thu, 29 Jun 2006 14:57:32 +0200 Subject: [PATCH] [S390] console_unblank woes. The software watchdog calls machine_restart from a timer function. The s390 machine_restart calls console_unblank to flush the console output. This is needed for panic to get the panic message printed. If console_unblank is called in interrupt a BUG is triggered in acquire_console_sem. That makes the software watchdog panic instead of restarting the machine. To get around this problem the call to console_unblank is made conditionally on !in_interrupt() || oops_in_progress.
