Hi Denis / all,
Do you know if there is a patch or lead for this problem? I seem
to be hitting same Oops with P730 lpar when running 4.8 (see below),
but 4.7.7 looks OK.

Jan

quoted Hi Denis / all,
Do you know if there is a patch or lead for this problem? I seem
to be hitting same Oops with P730 lpar when running 4.8 (see below),
but 4.7.7 looks OK.
Does this fix it?
Yes, it does. dmesg looks clean and network is up.
Regards,
Jan
