Hi,
I received the email that:"BOUNCE linux-kernel@vger.kernel.org: Message too long (>6000000 chars)".
To avoid missing the attached log, I put all the info in below link: https://github.com/xupengfe/syzkaller_logs/tree/main/221017_task_hung_in_fuse_lookup
It's reproduced in v6.0 mainline guest on TGL-H platform. The dmesg that reproduces the issue with the v6.0 kernel in the guest is also in the link above.
Thanks! BR.
