are system hangs normal?

[acunal....@gmail.com]

Hello All,

What I am working with

Qubes 4 Current Stable (7/19)
x230 with coreboot
Reinstalled to a new SSD a month ago

The problem -- Resolved temporarily by restarting

Several times a week there are times that without warning, everything is still up on the screen and will to a limited degree work, but it is as if it were a veneer of functionality. When I try to read/write the filesystem, make terminal / dom0 commands apps will either crash or no action will come. During the shutdown screen the verbose text hangs on waiting. Ctrl Alt Del returns text informing me that it attempted to restart the machine immediately and failed.
If something hasn't been saved or otherwise won't gracefully accept the table-flip of using the power button this is particularly unfortunate.

Questions

Thoughts on what this might be or where to look?
Is there a vocabulary for this type of problem?

In my experience hanging is quite rare.

However, there are certain (bad) conditions that can bring it about. For
example, if you mount external filesystems in dom0, and shut down the VM
that supplies the backing storage for the filesystem before its
un-mounted, then the system can become unresponsive in similar ways to
what you reported. Its not hard to forget to cleanly un-mount a
filesystem and close encryption, etc. before shutting down a storage VM.

There may be a different cause to your problem, but that is what came to
mind when I read your post.

No help from me.
I have a corebooted x230 - it's stable and always has been.
I havent tried Chris' method - I'll see if that triggers anything for
me.

Chris: Thank you for your thoughts

It just happened again less than an hour of up time while editing a plain text file.

while trying to open a dom0 terminal

"Failed to execute command "exp-open --launch TerminalEmulator" Failed to execute child process "exo-open" (Input/output error)

logout verbose text screen

"started account services Ctrl-alt-del pressed more than 7 times within 2s, rebooting immediately. watchdog: watchdog0: watchdog did not stop"

Unman: About how old would you say your Coreboot flash is?

[Chris Laprise]

What amount of RAM, and have you run a hardware test recently?

Does SSD pass SMART self-tests?

Did you install with the default (lvm) storage config? If so, are you
getting any errors about storage in the dom0 log?


If there appears to be nothing in particular causing it, you might want
to assume there was a glitch during installation. That has happened to
me before and doing a fresh install fixed it.

Not new. I cant remember exactly, but at least a year. Maybe more, I'm
ashamed to say.
