bookworm isn't as stable as buster

[hlyg]

i have tried bookworm,noticed many improvements

today it becomes unresponsive when i transfer files to cell phone with 
go-mtpfs

it doesn't respond to my keystroke, i can't see any error msg, disk LED 
in front panel of pc case shows busy, after about 5 minutes i disconnect 
power cord

i boot it again, last lines of journalctl shows phone connection thru 
usb, no error msg
