Panic in `BMCNativeCollector`

[mraerino]

Hi,

i just started testing the native collector on a fleet of nearly thousand hosts.

The exporter started panicing with this backtrace:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x6314be]
goroutine 14413 [running]:

this might be an issue in go-ipmi, let me know if i should report it there

@mraerino Hi～ I'm also experiencing this issue, freeIPMI works fine. Have you managed to solve it?

[mraerino]

Haven't investigated it more, we also switched back to freeipmi
