From: Kenji Kaneshige Date: Sat, 1 Sep 2007 07:36:26 +0000 (+0900) Subject: [IA64] Fix kernel panic in kdump on INIT X-Git-Tag: firefly_0821_release~25903^2~2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ac542a513bd7905fa1a700881e0a40a94d3ed46a;p=firefly-linux-kernel-4.4.55.git [IA64] Fix kernel panic in kdump on INIT Fix the problem that kdump on INIT causes a kernel panic if kdump kernel image is not configured. The cause of this problem is machine_kexec_on_init() is using printk in INIT context. It should use ia64_mca_printk() instead.
