[Kernel-packages] [Bug 1959529] Re: Hipersocket page allocation failure on Ubuntu 20.04 based SSC environments
This bug is awaiting verification that the linux/5.4.0-102.115 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Kernel-packages] [Bug 1959529] Re: Hipersocket page allocation failure on Ubuntu 20.04 based SSC environments
Thanks to Krzysztof, who spend some time to get this properly in, there is now a patched focal/20.04 kernel 5.4 available here: https://launchpad.net/~krzk/+archive/ubuntu/linux-testing https://launchpad.net/~krzk/+archive/ubuntu/linux-testing/+build/23143306 Since some more effort got spent like originally planned, it's needed and highly appreciated if this kernel can be tested and if we can get feedback if the issue is solved with it. -- 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/1959529 Title: Hipersocket page allocation failure on Ubuntu 20.04 based SSC environments Status in Ubuntu on IBM z Systems: In Progress Status in linux package in Ubuntu: In Progress Bug description: == Comment: #0 - D.
