Hi,
I have a brand new Dell PowerEdge 2850 (and a 1850 for that matters),
all running 2.6.17-rc3, on which I can't modprobe ipmi_si.
The kernel is a pure x86_64 kernel, compiled under debian sid amd64.
Here is the related dmesg when the modprobe is issued:
ipmi message handler version 39.0
IPMI System Interface driver.
ipmi_si: Trying SMBIOS-specified KCS state machine at I/O address 0xca8, slave
address 0x20, irq 0
Could not set up I/O space
Trying to free nonexistent resource <00000ca8-00000cac>
BT: timed out in B2H_WAIT [ SMS ]

BT: timed out in B2H_WAIT [ SMS ]

IPMI: BT reset (takes 5 secs)
BT: timed out in B2H_WAIT [ SMS ]
retry limit (2) exceeded
ipmi_si: Unable to find any System Interface(s)
modprobe is stuck for a while before giving the hand again.
What could be wrong, there ?
ipmi_si doesn't appear in the module list, only ipmi_msghandler.
removing ipmi_msghandler afterwards, produce the following oops, which
might be related to the fact that ipmi_si failed to load:

On 2.6.16, the problem is the same, except modprobe exits
immediately,but it still doesn't work:
server1:~# modprobe ipmi_si
FATAL: Error inserting ipmi_si
(/lib/modules/2.6.16-1-em64t-p4-smp/kernel/drivers/char/ipmi/ipmi_si.ko): No
such device
and the related dmesg:

I know this is not the expected result.
I tried to give several options to the modprobe command, but each time I
get the same problem.
If anyone wants to debug or help me solve this issue, I'm ready to
provide any material needed or test any patch, since the servers are not
in production yet.
Thanks,
Regards,
