Well, there should be no patch attached, yet. There was just an attempt to cherry-pick but it wasn't added to this LP. (And at least on LP there is no patch attached.) If you accidentally received one via the BZ bridge, please ignore and remove.
Anyway, appreciate your comment ... ** Attachment removed: "mm_page_idle.c_skip_offline_pages-backport.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904884/+attachment/5436359/+files/mm_page_idle.c_skip_offline_pages-backport.patch -- 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/1904884 Title: s390: dbginfo.sh triggers kernel panic, reading from /sys/kernel/mm/page_idle/bitmap Status in Ubuntu on IBM z Systems: Triaged Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: New Status in linux source package in Focal: New Status in linux source package in Groovy: Fix Released Status in linux source package in Hirsute: Fix Released Bug description: System hangs on dbginfo.sh script execution. Solution: Commit 92fb1db26eef ("mm/page_idle.c: skip offline pages") Included upstream since kernel v5.8, so it is already included in Ubuntu 20.10, but not in 20.04 and earlier. Commit 92fb1db26eef ("mm/page_idle.c: skip offline pages") applies cleanly on ubuntu-focal, but not on ubuntu-bionic. Adjustment / backport for bionic should be trivial, but it is not IBM code and therefore the backport will be requested here by Canonical.
