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:
```

In three stack traces I found
```
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
