ipmi on Dell PE 2850 fails, PE 1850 works fine

[Paul Dekkers]

Hi,

After using the ipmi module from -stable (or the port in most cases...)
on a couple of PowerEdge 1850's from Dell, I tried the same on the
bigger 2850... unfortunally, it fails. I updated the source-tree today,
and tried both SMP and GENERIC kernel.

On the 1850 I get:

ipmi0: <System Management BIOS> at iomem 0xf9900-0xf991e,0xf9920-0xfa5ba
on isa0
ipmi0: SMBIOS Version: 2.03, revision: 2.03
ipmi0: KCS mode found at io 0xca8 alignment 0x4 on isa
ipmi0: IPMI device rev. 0, firmware rev. 1.81, version 1.5
ipmi0: Number of channels 4
ipmi0: Attached watchdog

The 2850 gives me:

ipmi0: <System Management BIOS> at iomem 0xf9900-0xf991e,0xf9920-0xfa5bf
on isa0
ipmi0: SMBIOS Version: 2.03, revision: 2.03
ipmi0: KCS mode found at io 0xca8 alignment 0x4 on isa
ipmi0: couldn't configure smbios io res

But more scary, as soon as I unload the module (since it has no use
anyway ;-)) the kernel panics. Unloading ipmi from the 1850 works just fine.

Did anyone else stumble upon this issue? Any clues to debug? (I have a
kgdb output included below, but I'm afraid it lacks some detail.)

Unfortunally I only have this 2850 to test on (and I'm not sure how long
I can keep testing ;-)) - I tried multiple 1850's where things work as
expected. (Really happy with IPMI support there :-))
