Subject: 6.5.0rc5 fs hang - ext4? raid?
Hi,
I'm seeing a few hangs on a fs after upgrading to fedora 39's bleeding
edge; which is running kernel 6.5.0-0.rc5.20230808git14f9643dc90a.37.fc39.x86_64
It was always solid prior to that. It seems to trigger on heavy IO
on this fs.
The stack of this fs is:
spinning rust on SATA
LVM RAID 1
ext4
The host is a Ryzen 3950X.
Below is a sysrq backtrace of blocked tasks; this happened with
rhythmbox playing audio off the fs, while a meson build ran.
There was no oops or anything, just all the tasks on the fs hung.
I've got another case now where the only interesting thing running
is an 'ag' (parallel grep) running over the kernel tree.
(Anything not on that fs still seems to be running OK)
So it seems easy to trigger for me.
