I ran the error through decode_stacktrace.sh with the debug vmlinux file, and attached the result. The following line is where the first fault occurred:
RIP: 0010:zap_present_ptes.constprop.0 (include/linux/page-flags.h:284 (discriminator 2) mm/memory.c:1565 (discriminator 2)) This indicates that vm_normal_page is returning a non-NULL, but invalid struct page pointer. Then a call to page_folio on that invalid pointer is causing a fault. ** Attachment added: "incidente-2026-06-19-kernel_decoded-stacktrace.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2157705/+attachment/5978790/+files/incidente-2026-06-19-kernel_decoded-stacktrace.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2157705 Title: linux-hwe-6.17 6.17.0-35: kernel page-fault Oops in zap_present_ptes during exit_mmap; dying task leaves page-table lock + RCU read-side held -> RCU stalls + kcompactd soft lockup -> full system hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2157705/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
