Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: okurz@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 877944 --> https://bugzilla.suse.com/attachment.cgi?id=877944&action=edit dmesg of kernel panic especially shorttly after wakeup from STR on linux-default-6.4.0 showing "kernel BUG at ../lib/dynamic_queue_limits.c:27!" ## Observation Since about 2024-06-19 on my Dell Inc. Latitude 5300 2-in-1/0J9C2F, BIOS 1.19.0 12/14/2021, I observed multiple kernel panics, mostly either immediately or some seconds after wakeup from STR. After enabling kdump I could verify that every time the problem reported is "kernel BUG at ../lib/dynamic_queue_limits.c:27! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI". Currently running 6.4.0-150600.23.25-default. stack trace of latest recorded kernel panic: ``` [27011.816948] kernel BUG at ../lib/dynamic_queue_limits.c:27!

write_bulk_sg_callback+0xc7/0x1e0 [r8152 5053a9ece6fed4b24993dc907e4c2f28089d5aff] ``` so potentially the problem source is the network driver r8152 but maybe that's only a symptom. ## Reproducible Unclear. So far only observed on that device after some wakeups from STR, not all. Not fully reproducible yet. ## Expected result Last known good is possibly kernel-default-5.14.21-150500.55.52.1 from Leap 15.5 -- You are receiving this mail because: You are on the CC list for the bug.
