Title:
power-nv ppc64el need to blacklist shpchp
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Utopic:
Fix Released
Bug description:
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).
