Summary: shpchp: acpi_shpchprm:\_SB_.PCI0 evaluate _BBN fail=0x5 - HP xw8400 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=174893 [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[EMAIL PROTECTED] ------- Additional Comments From [EMAIL PROTECTED] 2006-01-24 14:02 EST ------- The error messages are coming from the SHPC hotplug driver complaining about a missing ACPI _BBN method. This method tells it the starting bus number under a root bridge. The BIOS on these systems is likely not creating the _BBN method since there is a single root bridge in the system, in which case the bus number may be assumed to start from 0. Are these systems expected to support SHPC hotplug? If no, the messages can be ignored since the system doesn't support this capability anyway. If yes, there are 2 fix options: 1) have the BIOS create the _BBN method under the root bridge 2) make shpchp assume that a missing _BBN implies bus numbering starts at 0 (untested patch attached). This patch will break on systems that have multiple root bridges or on systems where bus number does not start at 0, but such systems are already at risk because the ACPI root bridge driver also assumes the same thing. -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
