Hi Guenter,
Thanks for the report, it makes no sense to me though....
I can't reproduce it with QEMU git master, do you mind specifying your QEMU
version for me? Also is it possible to have a copy of dmesg when failure happens.
I currently use v9.0.2. I'll try with some other versions tomorrow.
A complete log is at
https://kerneltests.org/builders/qemu-mips64-master/builds/241/steps/qemubuildcommand/logs/stdio
Are you trying to instantiate an e1000 (or a variant of it) ? So far
I have only seen the problem with that controller. There is no specific
error message, the network interface just doesn't get an IP address.
I am able to reproduce the problem with qemu 6.2.0 (Debian build).
http://server.roeck-us.net/qemu/mips64/ should have everything needed to
reproduce it. "repeat.sh" repeats the test until it fails.
Hope this helps,
Guenter
