[Bug 1374440] [NEW] power-nv ppc64el need to blacklist shpchp

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

The shpchp module seems to be causing issues on some ppc64el hardware.
We're able to work around the issue by blacklisting it as:

$ cat /etc/modprobe.d/blacklist-ppc64el.conf
blacklist shpchp

I've discussed this with Anton, and we came up with the above work around.
I'll attach a log of the failed boot.   Note, that the shpchp.blacklist=yes command line parameters seem not to do anything (ie, just ignore them).
