The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

--- Comment From tyr...@us.ibm.com 2020-08-24 12:34 EDT--- (In reply to comment #24) > 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). Understood, but is it possible to get a one-off/test kernel in the interim? We have cloud customer for whom this problem is causing intermittent outages. > > Am I got it right reading that this happens on PowerVM DLPARs, controlled by > PowerVC? Correct, but the problem isn't limited to that scenario. It can be recreated on any PowerVM LPAR, but hvcs is generally not used outside of PowerVC setups and as such that is where this got exposed. --- Comment From tyr...@us.ibm.com 2020-08-24 12:37 EDT--- (In reply to comment #25) > I saw that the tag 'targetmilestone-inin16046' is set, which points to 16.04 > as affected release. Is this the only affected Ubuntu release? This is the LTS that PowerVC uses, but as mentioned previously this issue effects all PowerVM LPARs should someone choose to use hvcs so it is desirable in any other releases that support PowerVM. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1892546 Title: Novalink (mkvterm command failure) Status in The Ubuntu-power-systems project: Triaged Status in linux package in Ubuntu: New Bug description: -- Problem Description -- drmgr command is failing while trying to open console for IBMi.
