So this isn’t related to the half hang issue?

Not at all. This issue was about USB resets happening occasionally when the modem attempted to wake itself up from USB suspend. You would see it disappearing from the bus and appearing back a moment later.
Was the talk not clear enough? Let me hear some feedback

No the talk was clear but I thought this half hang issue was related to the USB bus. My mistake.
EDIT: I see the new “Network Problems” issue you created. Thank you! I guess it’s actually this issue you created:

The “half hang” (the problem that can result all sorts of erratic behavior, such as “sudo” hanging, the phone not suspending anymore etc.) is a result of use-after-free that’s happening in CDC-NCM gadget that implements the network interface over USB-C port. I haven’t really traced the whole execution path yet, but I found a recent patch on Linux mailing lists that was described to fix such an issue: Draft: usb: gadget: f_ncm: Fix Kernel Panic due to access of invalid gadget ptr (!769) · Merge requests · Librem5 / linux · GitLab. This is a USB gadget, but ultimately the problem is not really related to USB - the same bug with the same consequences could end up in any other driver.
There’s also the issue with cellular network connection getting stale (not receiving any incoming packets). This is actually related to USB power management (as in: this is what can trigger it), but so far it looks like the problem actually happens on the modem side rather than the host (but I don’t have any conclusive proof yet).

She is paid for work on something that could benefit PureOS in 2025. No tears.

I moved on May 30 from one L5 to another. The new L5 has the SparkWLAN card, the older Redpine. Both are otherwise identical in kernel and below /home/purism. Since this, I faced no hangup when returning from suspend.
Another observation (as feeling) is, that the new L5 with this card draws more battery power when the L5 acts as Internet AccessPoint and is otherwise unused (display off, no apps running). I will do an exact measure when the device returns from display swap.

Any ETA to bring back @dos for Purism?
I’m very nervous about losing @dos and dos go far away for other company.

Senior leadership at Purism greatly appreciates @dos’s work and is eager to ramp up billable hours as soon as financially viable. I scheduled a meeting with leadership for Thursday to sync up and kick off planning R&D efforts (more from a financial planning and high-level project management perspective at this time).

The half hang thing which I thought had something to do with the USB port issues. When I connect my Nexdock it will do this when I unplug or replug it.

Tested and it really work amazing. ( ! ) s2r.data bug it gone.
Fixed too.
If u want testing downloads packages below then install all: ‘sudo dpkg -i *.deb’ on Librem 5 then Reboot, check gsm.data box before and after s2r.
Gnu Byzantium download only.
All packages were processed from Petitboot System.
