This is an addendum to Bug #59321 which got fixed. Same hardware (Haswell step 2, i4570, MSI-7817 B85m mainboard. Here's the challenge: Occasionally (about every fifth time) when I do S4 suspend and resume cycle, after resuming I have no network, meaning the interface is not coming up again.

Any news on this bug? It still happens with 3.18.0rc6 (a834a782adf3ab4b508cd80e9082960263bcc4ed), see also https://bugs.freedesktop.org/show_bug.cgi?id=82864. Thank you!
This still happens with 4.2 kernels, even after updating the BIOS to 10.9 and resetting all BIOS settings to default. How can I help debug this problem? It basically prevents us from using S4 suspend at all, since without networking, the computer is not really usable. Thanks!
