On all kernels 5.15.x and 5.16.x I noticed that resetting
the USB devices with this shell script:
for i in $(ls /sys/bus/pci/drivers/ahci/|grep :)
do
echo $i
echo $i >/sys/bus/pci/drivers/ahci/unbind
sleep 1
echo $i >/sys/bus/pci/drivers/ahci/bind
done
# reseting USB3 ports (if there none you'll get errors)
for i in $(ls /sys/bus/pci/drivers/xhci_hcd/|grep :)
do
echo $i
echo $i >/sys/bus/pci/drivers/xhci_hcd/unbind
sleep 1
echo $i >/sys/bus/pci/drivers/xhci_hcd/bind
done
immediately leads to a non-functional system, because the discs
face I/O errors and will switch to read-only mode.
Effectively I have to reboot the machine.
It's reproduceable for me on two completely different x86 machines with
different USB devices.
