said Dr. Nikolaus Klepp via tde-users:

| 1) make a backup - just in case it's your harddisk that's dying.

check.

| 2) run memtest.

strangely, memtest no longer appears in my grub menu, and i have no memtest 
executable. 

| 3) preoare a backup machine

that might be a big bite.

| IMO when things die unexpectidly while powered up it's
| hdd/ram/somecard/mainboard in this order.

we'll see if it repeats. i very much hope it doesn't. i wondered if a log 
i've had running -- a ping every three seconds with the result written to 
disk -- might have stressed something. and it has on occasion over the 
years suffered from what seems to be something overheating, such as when 
it tries to compile a heap of nvidia modules. 

| The error on r8169: that's a bug of the hardware or kernel, not sure
| which to blame. It leads to dropping network connections now and then
| and with network-manager the kernel modul crashes when you have wifi
| enabled and plug in the lan cable. I notized it to appear ~ 2 months ago
| (amd AMD Ryzen 7 PRO 4750U on lenovo T14 AMD gen1). You can work around
| it with "pcie_aspm=off pcie_port_pm=off" added to /default/grub.

yeah, i kind of figured that out -- i have disabled the onboard networking 
in favor of a standalone card and imagine it's that. what i don't 
understand is why boot stopped entirely with the check of /dev/sda1, which 
it found to be okay but then did not proceed, and why everything works if 
i boot into rescue mode -- again, from my grub menu, not from a usb drive 
or anything. and right now it is the only drive in the system.
