F33 just pretends to print
by Michael Hennebry
I have a Brother HL-L2360DL that I'd thought I'd finally managed to install.
I had to go to the Brother website to get a script to run.
The instructions for the script had the wrong name for it.
None of the default options for Brother printers came close.
The CUPS adminstration "web" pages say the right things:
Idle, accepting jobs, two completed jobs.
Nothing actually prints. Not even a test page.
The printer never comes out of deep sleep.
How do I fix this?
It worked with Centos 7, but I do not know what I did.
In my experience, there is no such thing as a small problem when it comes to
installing a printer on Linux:
Either it just works or it requires a mighty effort.
I am getting mighty tired of mighty efforts.
BTW how do I change the default from single- to double-sided?

Improper shutdown, now Kernel panic.
by murph nj
Hi all:
I've got an odd problem that I was hoping for some help on.
The laptop was previously working fine, I am running F30, updated regularly.
I've got an Acer laptop that has been shutting down suddenly. (I
suspect a bad battery, working on that.)
After a sudden shutdown last night, I now get a kernel panic on boot
right after "Starting Switch Root..."
I was able to boot from a USB stick, and was able to read the journal,
but I didn't see anything obvious to help.
I was able to get all of my data off of the (encrypted) disks, so
that's not a problem, but I don't want to just give up, and wash and
reload too quickly.
Any suggestions?
Thanks,

LUKS on shutdown.
by murph nj
I'm having an issue shutting down. Fedora 34, just updated to 35, same
problem. (It was around in 33 as well, I've been putting up with it.) I
know that there is another list for beta versions, but this issue was there
in the current version as well.
Somewhere around 1 out of every 10 shutdowns, the system goes down to
"[ OK ] Reached target System Shutdown", but then,
"[ *** ] a stop job is running for Cryptography setup for luks-<cycle
through LUKS volumes>"
It typically goes for about 1/2 hour if I don't get fed up, and hold the
power button down.
I just saw after that 1/2 hour:
[Time] Timed out starting System Reboot
Forcibly Rebooting: job timed out.
audit: type=1334.........
I still had to power it off. On reboot, it seems OK.
I haven't found anything interesting in /var/log/messages regarding it.
Any suggestions to further troubleshooting?
Thanks,

NFS mount lockups since about a month ago
by Terry Barnaby
Hi,
I use NFS mount (defaults so V4) /home directories with a simple server
over Gigabit Ethernet all running Fedora33. This has been working fine
for 25+ years through various Fedora versions. However in the last month
or so all of the client computers are getting KDE GUI lockups every few
hours that last for around 40 secs. /home is not accessible during this
time and it feels/looks to be an NFS lockup issue. There are no "NFS
server no responding" or such like messages in either the servers or
clients /var/log/messages and the network communications seems fine.
1. Have there been some changes to NFS recently in the kernel ?
2. Any idea where to begin to try and debug this ?

Cockpit login fails

Hi,
I tried to use the cockpit on fc34, but the login fails:

Unfortunately I did not find anything regarding the

issue. /etc/pam.d/cockpit exists and there is also no customized pam
configuration.
Any ideas?
Best Regards
