Hi All,
I have been seeing lockups reliably occur on v6.12-rc1, 3, 4 and linus'

stuck for 33s!

My config:

early (available) dmesg is below.

Thanks for report. This doesn't remind me of anything but checking the
writeback changes we have merged 532980cb1bf ("inode: port __I_SYNC to var
event") which could have odd consequences if we made mistake somewhere...
It probably won't be easy to revert but you could try whether the problem
reproduces before / after this commit.

BTW, can you please share logs which would contain full stacktraces that
this softlockup reports produce? The attached dmesg is just from fresh
boot... Thanks!

thanks for getting back to me.
So I think that enabling /proc/sys/kernel/softlockup_all_cpu_backtrace
is required there. Unfortunately my VM often just locks up without any
sign of life.
But I'll continue to try. And I'll also try reverting that commit you
mentioned.
Cheers,
John

Attach a "serial" console to the vm - add "console=ttyS0,115600" to
the kernel command line and add "-serial pty" to the qemu command
line. You can then attach something like minicom to the /dev/pts/X
device that qemu creates for the console output and capture
everything from initial boot right through to the softlockup traces
that are emitted...

I am using an OCI instance, so I can't change the qemu command line (as
far as I know).
For this issue, the Cloud Shell locks up also. There are other console
connection methods, which I can try.
BTW, earlier today I got this once when trying to recreate this issue:
