We are using kernel 5.10.7 in the latest Tumbleweed version. The latest iso image is available under: https://download.opensuse.org/ports/zsystems/tumbleweed/iso/

Hmm, it says "5.10.5-1-default" in the kernel BUG output. In order to match the given line 2144 from "mm/huge_memory.c:2144" and to find the corresponding kernel code, a matching kernel source would be needed. Is there any other means of kernel source access for openSUSE Tumbleweed, ideally a git repo like for SLES? Seems hard to believe that "open"SUSE kernel source is harder to find / access than SLES code... Anyway, SUSE developers surely have such access, and since this is BUG statement in common memory management code anyway, I would suggest to let one of the corresponding SUSE developers have a look first. BTW, some information that might help is the fact(?) that THP worked fine on s390 with Tumbleweed, at least for some very short time, when verifying the other THP fix in LTC bug#184202 / SUSE bug#1163684. IIUC, then it was verified there with 5.9.11, but that is not 100% clear to me from the other bugzilla. Please verify on which kernel version it worked fine the last time. Then, with having access to some proper source repo (and not just an ISO), one might be able to see what was changed in between and with regard to THP, maybe madvise. -- You are receiving this mail because: You are the assignee for the bug.
