6.8.2 hangs on startup

Hi,
just updated my Arch system, upon reboot it started hanging at boot.
Systemd starts every service correctly but at the end it won't switch to the login manager. It hangs on the latest console message for a while, then the following errors are displayed. TTYs aren't accessible yet so I need to force the shutdown with the power switch.

This is from journalct, errors on boot are less detailed.

It happens only with kernel 6.8.2 both mainline and zen. Downgrading to 6.8.1 works properly and I can't figure out what's causing the issue.

Haven't found a bug report for this anywhere.

Any hints? Or just try next kernel release?

The warnings there are about hanging tasks - they're most likely symptom and not indicative of the cause.

Re: 6.8.2 hangs on startup

"intel_iommu=on iommu=pt"
Why?

You're not even reaching the multi-user.target, syncthing is operating and netfs loaded and there's a prodigynas - does this happen if you disable syncthing and do you (auto)mount some NFS?

Why?

I needed those options for the pci passtrough on a VM of the wireless nic. Currently the related vfio module is disabled so its doing nothing. I also tried removing those options from kernel parameters with no difference.

I did some testing after your reply.

Updating the kernel brings out this issue and won't get me to the multi-user so not even a TTY to fix it and do some troubleshooting (had to chroot from a live yesterday to downgrade the kernel).
I tried installing linux-lts to have a "backup" kernel to boot into. Well, latest release 6.6.23-1-lts has the same problem but 6.6.22 don't, both 6.6.23 lts and 6.8.2 mainline/zen kernels were released the same day so it tracks.

- Disabling Syncthing changes nothing (prodigynas is the debian machine I use as a media-server/NAS > also a syncthing client)

- Commenting out from fstab all the lines for the auto-mount of all the samba shares (from the NAS mentioned above) fixes the issue. I use Samba for accessing those folders from windows PCs.
Here's an example of one of the fstab entries:

//10.0.0.10/public  /mnt/NAS/public         cifs    credentials=<redacted-cred-file>,_netdev,uid=bucch,gid=bucch,vers=3.0,x-systemd.after=network-online.target     0       0

There's maybe something new/deprecated in cifs or whatnot I haven't read about yet?

Re: 6.8.2 hangs on startup

There's nothing special in that line - you could try to set it "noauto" and maybe remove the x-systemd condition and then to manually mount it after the boot completed.
Maybe that throws you a usable error.

I had the same thought after posting my last reply. Here's the results:

- Removing x-systemd.after=network-online.target > still FAILS
- Removing _netdev > still FAILS
- Adding noauto > WORKS, of course

Manually mounting one or more shares after booting with noauto doesn't return any error and works correctly.
Journal output while manually mounting is the following

mar 29 21:53:48 NZXT kernel: FS-Cache: Loaded

Seems this user has a similar issue but with encrypted swap: https://bbs.archlinux.org/viewtopic.php?id=294360

EDIT: there were some cifs fixes upstream in both 6.8.2 and 6.6.23 https://git.kernel.org/pub/scm/linux/ke … 5a096762e4 maybe that's the culprit.

The network-online.target's all don't really do what you think by default

My general strategy for remote mounts is to use "noauto,x-systemd.automount"

Thanks for the tip. My setup was done long time ago while tinkering for the first times, probably found somewhere online, and I carried it over from distro to distro since then.
For completeness of information, I also tried x-systemd.after=multi-user.target and it just hangs while in SDDM.

I've now set up fstab like you suggested and since it mounts the shares only when needed (right?), after the user session is already started, doesn't cause the issue. I think I'll keep it this way from now on.

I'm just concerned this odd behavior is likely caused by a bug, mounting shares during boot shouldn't hang the system. Linux upstream reports had to be done through distro's trackers but unfortunately the Arch one had new user registration closed.

Re: 6.8.2 hangs on startup

"On access", right.

but unfortunately the Arch one had new user registration closed

This isn't a packaging bug anyway and would get closed as such.
=> https://bugzilla.kernel.org/buglist.cgi?component=CIFS

I'd not be surprised at all if this is the patch you linked and you're running into that condition (full write buffer) because the mount fails/lags due to the missing network connection (which is also why the multi-user.target would be futile)
You could try your previous setup but w/ "wsize=8192000",  https://man.archlinux.org/man/extra/cif … size=bytes
(There's no guarantee that this works but it will create more wiggle room)
