Subject: CDC ethernet gadget: complete system freeze
Date: Tue, 10 Mar 2020 09:43:07 +0000 [thread overview]
Message-ID: <17c670a4386bc1cfa3db207c6961d95f3378ad64.camel@infinera.com> (raw)
We have an embedded T1042 NXP CDC ethernet gadget which seems to completely freeze when an
usb0 I/F is established and one do 1 of two things:
1) reboot the connected Linux laptop -> CDC gadget appears to enter complete system freeze.
2) on laptop, ifconfig usb0 down; rmmod cdc_ether -> CDC gaget freezes
I cannot finns and OOPS or other trace in console or syslog. I could really use som ideas here.
Linux kernel 4.19.108 (4.19.76 has the same issue)
