Re: Still a pretty bad time on 5.4.6 with fuse_request_end.

[Miklos Szeredi <miklos@szeredi.hu>]

Hi,

Thanks for the report.

Is this readily reproducible?

Can you please do an "echo t > /proc/sysrq-trigger" after you see the
hang, and send the output.   Make sure you have enough dmesg buffer:

 - either add "log_buf_len=4M" to the kernel boot command
 - or recompile the kernel with CONFIG_LOG_BUF_SHIFT=22

Thanks,
Miklos
