Version 15 of the Linux IPMI driver

This is yet another release of the IPMI driver for Linux. This is for linux 2.4.20 and 2.5.50, patches are available from the previous release (Version 14) of the IPMI driver.

This release of the IPMI driver fixes some race conditions on SMP systems, and fixes some minor problems in the watchdog. A special thanks goes to Francois Isabelle at Kontron for finding the SMP problem and helping me debug it.

The NMI handler has changed to export the nmi_watchdog variable; since the ipmi watchdog is incompatible with the IOAPIC nmi_watchdog setting, it detects this and refuses to use NMI in that case. As usual, you don't need the NMI patch if you don't care about IPMI NMI watchdog pretimeouts, but you must upgrade to the new NMI patch if you use the IPMI NMI watchdog pretimeout.

As usual, you can get the drivers from SourceForge. The home page is
http://openipmi.sourceforge.net.

http://sourceforge.net/projects/openipmi gets you directly to the page with the patches.

PS - In case you don't know, IPMI is a standard for system management, it provides ways to detect the managed devices in the system and sensors attached to them. You can get more information at
