Re: [Freeipmi-users] querying sensors of Intel SE7210TP1-E board fails with ipmi_sdr_cache_create: internal IPMI error

[Albert Chu]

Hi Werner,

I've personally never worked on a machine that uses an SSIF interface,
so I'm unsure if there could be a bug in the SSIF code.  It's certainly
possible.  If the user could recompile freeipmi with --enable-debug
--enable-trace in ./configure, we could get a lot more debugging info.

However, in the meantime, I think the easiest thing this user can do is
to simply use the IPMI kernel driver.  FreeIPMI checks if the IPMI
kernel driver is loaded (/dev/ipmi0) and uses it.  In fact, it favors
the kernel driver over it's internal drivers if it is found.
