Hi, since 7.3.2 my USB RTL8157 runs for a short while and then crashes completely.

I’ve noticed the following: with < 7.3.2 i reached only CPU-Package-C9, but now I reach C10.

Is the driver package "RTL8152 Drivers" disabled ?

Before I start debugging myself, I wanted to ask the experts first.

Maybe this has something to do with:

Linux Kernel

The Linux kernel has been upgraded to 6.18.38-Unraid. This release also sets CONFIG_USB_AUTOSUSPEND_DELAY=-1.

greetings

cat /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port1/usb3_lpm_permit

cat /sys/bus/usb/devices/2-1/power/usb3_hardware_lpm_u1

cat /sys/bus/usb/devices/2-1/power/usb3_hardware_lpm_u2

-> says that the energy-saving option is activated

I disabled it with:

echo 0 > /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port1/usb3_lpm_permit

but I don't know why this is necessary after update 7.3.2 !?

Can you elaborate on that? Is my fix correct?

Depending on which version of unraid you updated from, the linux kernel had a jump in versions which could have introduced driver changes to the network driver or USB drivers. If blacklisting the sleep function makes it work then yes that is the correct solution. Just keep in mind this behavior can change when when unraid updates and uses a newer linux kernel.

I marked my workauround as solution, even though I find it unsatisfactory and am surprised that no one else has this problem / uses the USB NIC.

Ill be honest, I dont think many people use USB NICs and the user pool on the unraid forums is pretty small.

I would suggest checking a mainline linux forum (arch forums for example) for questions/answers for something Linux Kernel related.
