[PATCH]: powerpc: pseries: Print PCI slot location code on failure
From: Linas Vepstas <hidden>
Date: 2006-06-15 22:15:30
Resending an older patch (from 28 April) that seems to have fallen through the cracks, its not in mailine, is not in -mm and its not controversial (its mostly a printk change). Tested. --linas 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.
