I had a try on kernel 4.15.0-46 in Bionic with efi-pstore module loaded as pstore backend, but I cannot reproduce that kernel panic. It really takes more information before one can investigation more into this issue, so apport runs, even before the panic taking place, is really mandatory. Please give apport a chance to collect some more information by executing `apport-collect 1821434`.
By the way, have you tried to enable efi-pstore _without_ that SATA card installed. Maybe it's not related to efi-pstore at all? ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821434 Title: Panic on suspend/resume Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: sata_pmp_eh_recover+0xa2b/0xa40 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1821434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
