Bug ID: 232549
Summary: IPMI driver will attach, but ipmitool and commands
sent to the device fail.
Product: Base System
Version: CURRENT
Hardware: powerpc
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: sbr...@freebsd.org
The Tyan PPC hosts we have in the freebsd cluster are administered via IPMI. I
recently added "device ipmi" to our default kernel configuration to test out
local interactions with /dev/ipmi0:
ipmi0: IPMI device rev. 1, firmware rev. 1.10, version 2.0, device support mask
0xbf
ipmi0: Number of channels 2
ipmi0: Attached watchdog
ipmi0: Establishing power cycle handler
The attach will emit one or two errors at startup that are only visible on the
console:
[464515.035780175,3] BT: seq 0x6f netfn 0x06 cmd 0x42: Maximum queue length
exceeded
[464515.036165129,3] BT: seq 0x6e netfn 0x06 cmd 0x42: Removed from queue
When attempting to interact with /dev/ipmi0 via ipmitool lan print, the
following spew occurs:
r...@archon.nyi:~ # ipmitool lan print

---- errors continue for several pages.
I'm going to make the "bold" assumption that ipmi(4) has never been used on a
BE system or at least on one recently.
