After an update using the graphical application with Mobian my mechanical keyboard does not work. The on-screen keyboard does work, however.
One of the updated files had something to do with the keyboard.
If anyone has experienced the same problem and can offer a suggested fix please do so.

I had the same issue today with the kernel 5.15.41 apparently («uname -a») compiled on May 25. It also seems to break docking.
I see two options: find the previous version in /var/cache/apt/archives and install it; or go to /etc/apt/sources.list.d/mobian.list to copy the repo line and replace bookworm with unstable in the copy, then after apt update install linux-image-5.17-sunxi64
I used the latter option, now typing this reply from the PinePhone using an external keyboard but some words in this replied are typed on the PinePhone hardware keyboard…
(about my debugging findings: normally there is a kb151 module, the linux-image-5.15-sunxi64 package with kernel version 5.15.41 seems to lack it)
Thanks zltpxqhp69o2. I may try one of your suggested fixes if I get my courage up.
In the interim I hope someone who maintains Mobian sees these posts and issues an update that addresses the problem.

True that — I run all the things off an SD card anyway.
Disappearance of keyboard from power sources and lack of keyboard functionality is in line with what I have observed with the kernel that misses the drivers.
If «sudo lsmod | grep kb151» finds nothing and «sudo modprobe kb151» says the module is not found, I think you can be pretty sure you have the software issue, which does not exclude a hardware issue but puts its chances to the baseline.
About Mobian just fixing things — the unstable kernel package might indeed end up being promoted to bookworm in some time. A week or two maybe? Or has almost enough time passed already anyway? Not sure if this topic would change the timing. Maybe report the bug in their tracker and post the link here?
Many thanks to everyone in this thread for all the information. I also experienced this issue and was trying to diagnose it as it definitely looked like a botched Mobian update. Both kb151 and ip5xxx_power modules are now missing from the /lib/modules/5.15-sunxi64/kernel subtree. Great to hear that the Mobian maintainers have already been notified.
Is there any information as to when the fix will be released into the wild?
Which Matrix client(s) work (best) under Mobian on the PinePhone?
