any of the commands in util_ cause igb to wedge on debian 10 / pcengines apu3c4 #10

Closed peril99 closed 4 years ago

peril99 commented 4 years ago

this appears to be a bug between the kernel -ethernet driver, and the semtec utility code which causes the ethernet driver to wedge

Testing with pcengine apu3c4 - firmware v4.12.0.4 Debian 4.19.132-1 x86_64

kernel error during the run ... [snip] root@debian:/home/peril/src/picoGW_hal# ./util_chip_id/util_chip_id 333833302axxxxxx [ 106.518057] igb 0000:02:00.0 enp2s0: PCIe link lost root@debian:/home/peril/src/picoGW_hal# ping 192.168.20.5 PING 192.168.20.5 (192.168.20.5) 56(84) bytes of data. ^C --- 192.168.20.5 ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 29ms

Is this driver smp safe?

I'm going to go backwards from debian9, debian8 to see if this is a bug introduced with later kernels.

I don't believe that this is the igb driver anymore - think that this is could be bad hardware. looking to isolate via a usb based ethernet adaptor - if that works - likely h/w.

peril99 commented 4 years ago

ok - after moving to an alternate usb based driver - the card works fine with the us based legacy packet forwarder - this is most likely a problem with APU igb hardware. closing issue
