From 0aa8d15b01881ccaab5f2fb31eef33ced97ccb5f Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Mon, 19 Jun 2006 15:07:40 -0500 Subject: [PATCH] [POWERPC] pseries: Print PCI slot location code on failure The PCI error recovery code will printk diagnostic info when a PCI error event occurs. Change the messages to include the slot location code, which is how most sysadmins will know the device.
