Bug#735139: [Nbd] nbd recovery after suspend/resume
Hi Paul, Op vrijdag 21 februari 2014 22:54:43 schreef Paul Clements: Is it a kernel related thing, or could it be the fix to nbd-client signal handling as detailed in this thread? I doubt that it is userspace-related. When reading the bug log, no mention is made of changes in userspace, only of using a more recent kernel. However, that doesn't mean there are no such changes. Ernesto, did you change anything in the way you ran the NBD device? If not, can you clarify how exactly you're establishing the client side of the NBD connection?
