Hi all, The IPMI support in newer RedHat kernel updates from (at least) 2.6.9-78.0.8 seems to be broken for BT-type devices (such as the Dell Poweredge 1750). This means that neither ipmitool nor OpenManage 5.5 on this system work correctly. The problem shows up, when the Dell dataeng service is starting, causing the IPMI drivers to be loaded. For example, on a 2.6.9-78.0.1 kernel, the following appears in the logfiles: Aug 11 15:00:27 qaap600a-02 kernel: IPMI System Interface driver version 33.13, KCS version 33.13, SMIC version 33.13, BT version 33.13 Aug 11 15:00:27 qaap600a-02 kernel: ipmi_si: Found SMBIOS-specified state machine at I/O address 0xe4, slave address 0x20 Aug 11 15:00:27 qaap600a-02 kernel: ipmi device interface version 33.13 Aug 11 15:00:56 qaap600a-02 kernel: input: PC Speaker Aug 11 15:01:21 qaap600a-02 kernel: BT: timed out in WR_BYTES [ B_BUSY H2B ] Aug 11 15:01:21 qaap600a-02 kernel: restart command Aug 11 15:02:16 qaap600a-02 kernel: BT: timed out in WR_BYTES [ B_BUSY H2B ] Aug 11 15:02:16 qaap600a-02 kernel: restart command Aug 11 15:03:07 qaap600a-02 kernel: BT: timed out in WR_BYTES [ B_BUSY H2B ] Aug 11 15:03:07 qaap600a-02 kernel: retry limit (2) exceeded Aug 11 15:03:07 qaap600a-02 kernel: IPMI: BT reset (takes 5 secs) Aug 11 15:05:04 qaap600a-02 kernel: BT: timed out in WR_BYTES [ B_BUSY H2B ] Aug 11 15:05:04 qaap600a-02 kernel: retry limit (2) exceeded Aug 11 15:05:04 qaap600a-02 kernel: Trying to free free IRQ10 Aug 11 15:05:04 qaap600a-02 kernel: ipmi_si: Unable to find any System Interface(s)
With a 2.6.9-78 kernel, the ipmi_si driver loads correctly and the kernel log file shows something like this: Aug 18 00:39:11 qaap800a-02 kernel: IPMI System Interface driver version 33.13, KCS version 33.13, SMIC version 33.13, BT version 33.13 Aug 18 00:39:11 qaap800a-02 kernel: ipmi_si: Found SMBIOS-specified state machin e at I/O address 0xe4, slave address 0x20 Aug 18 00:39:11 qaap800a-02 kernel: Using irq 10 Aug 18 00:39:11 qaap800a-02 kernel: IPMI bt interface initialized Aug 18 00:39:11 qaap800a-02 kernel: ipmi device interface version 33.13 Is there a newer driver, or some other way to resolve this issue? Suggestions appreaciated! thanks, Andrew
