Bug Description
SRU Justification:
[Impact]
* drmgr command is failing while trying to open console for IBMi on PowerVM LPAR
[Fix]
* 63ffcbdad738 "tty: hvcs: Don't NULL tty->driver_data until hvcs_cleanup()"
[Test Case]
* Create a VM from PowerVC on a Novalink managed host.
* Unmanage and manage the VM, this problem gets reproduced.
* grep the logs for "drmgr"
[Regression Potential]
The regression can be considered as very low, since:
* limited to the IBM Hypervisor Virtual Console Server.
* patched kernel where shared and successfully tested by IBM.
* the worse case, if the cleanup is broken a new opened connection might break.
[Other]
* The patch got upstream accepted.

To post a comment you must log in.
It looks like the patch just got submitted to upstream (and landed in a staging tree); but we usually need to wait for it's upstream acceptance - at least to Torvalds tree or linux-next (to be sure that the patch is stable, reviewed and community accepted).
Am I got it right reading that this happens on PowerVM DLPARs, controlled by PowerVC?
