[BUG REPORT] kernel BUG at lib/dynamic_queue_limits.c:99!

[xiujianfeng]

I found a problem with my QEMU environment, and the log is as follows.

After I did the bisect to locate the issue, I found
8490dd0592e85e0cceefa6b48d66dbdd73df0fb3 is the first bad commit,
however this is a merge commit, and I cannot further confirm which
specific commit caused this issue.
