I've not seen this issue with 6.4 kernels. I started to use the 6.5 series from
version 6.5.3 onwards, but I think I first saw this error with 6.5.5 or 6.5.6.

--- Comment #3 from jaak+bugzilla.kernel.org@ristioja.ee ---
The mount line for root I already posted was this:
/dev/nvme0n1p2 on / type ext4
(rw,noatime,nodiratime,nodioread_nolock,discard,nodelalloc)
I'm sorry, but I recreated the root partition for safety. However, here's the
dumpe2fs output on a binary copy of the old failing partition (only label
changed with tune2fs -L):
# dumpe2fs -h /dev/vg/root-old

However, the issue seems to occur on the newly-created root as well:

The new root filesystem was created with mkfs.ext4 with no special options.
Here is the relevant /etc/mke2fs.conf:
[defaults]

inode_size = 256
inode_ratio = 16384

}
ext4 = {

}
small = {
blocksize = 1024
inode_ratio = 4096
}
floppy = {
blocksize = 1024
inode_ratio = 8192
}
big = {

huge = {

--- Comment #6 from Theodore Tso (tytso@mit.edu) ---
It would be really nice to get a translation from the stack trace offsets to
line numbers, but what appears to be happening is that we're starting a journal
commit, and to complete the journal, since we are in the default data=ordered
mode, we call ext4_journalled_submit_inode_data_buffers(), which in turn calls
write_cache_pages() to flush out modified data blocks associated with an inode
which had newly allocated blocks (so that we don't accidentally expose stale
data blocks if there is a crash, which is a guarantee of data=ordered mode).
The write_cache_pages() function is then calling some function in mm/filemap.c
(this is where a line number translation would be happy), which calls
folio_wait_bit_common(), which presumably is waiting for some memory folio
which is undergoing writeback, or otherwise busy, to complete. This then
calls io_schedule() --- because we're waiting for some I/O to complete, and
this apparently never completes, thus stalling the jbd2 commit operation, and
then all of the other processes which are trying to make changes to the file
system are waiting for the commit complete, leading to all of the other stack
traces.
The question is why is this happening on your system? It could be because of
some kind of missed I/O completion interrupt, or some other problem in the
block device layer or NVMe driver ---but normally if that were the case, there
should have been some kind of kernel log messages from those parts of the I/O
stack. Were there any that you could see (that perhaps were excerpted out in
the bug report, since "obviously" it was assumed this was an ext4 problem, as
opposed to ext4 simply being an innocent victim of problems lower down on the
storage stack?
The other question that might be worth asking is what sort of workload does
your server run, and how might this be different from what other users might be
doing, or what we exercise with out regression tests?

--- Comment #7 from jaak+bugzilla.kernel.org@ristioja.ee ---
I'm not running anything special on the server, it is a KVM/libvirt host with
only a few VMS, none of which use the root filesystem for storage. Besides that
it is only the usual set of system services and ssh for admin access, so I
think most writes to the root filesystem are due to logging.
I compiled and rebooted to a new the 6.5.7 kernel with only
CONFIG_DEBUG_INFO=y, CONFIG_DEBUG_INFO_DWARF5=y and
CONFIG_DEBUG_INFO_COMPRESSED_NONE=y added, but the issue has not yet
re-occurred during the almost 3-day uptime.
