Fedora got a bug report of a crash in IPMI on 4.15.6
Unfortunately, it's only a screenshot but it's fairly
clear. It looks like a panic in the error handling path
in platform_device_unregister. Any ideas?

You may also run into another issue.  You can pull the
individual patch at

https://github.com/cminyard/linux-ipmi.git c8a1972e77dbe321ce5ce0247056e727234cbaec

Actually, it needed a few more tweaks.  Can you do change
instead?  It's "ipmi: Fix some error cleanup issues"

I can send you patches, if you like.  If you could test and get back
to me, that would be great.

Laura, have you had a chance to test this?  I'd like to get it in soon,
if possible.



BTW, the IPMI setup in your system is incorrect.  SMBIOS says it's at a
memory address, but it's at an I/O address.  And the address given
doesn't appear to be a valid address, the value read doesn't appear
to be a valid value.


for that fix.


Yeah, this is fixed by 174134ac7602 "ipmi_si: Fix error
handling of platform device" in mainstream.

I guess I need to request a backport of this.

Thanks for reporting.
