Most excellent! Take your time for testing - unfortunately we missed
the v3.0 train already but it would be great if we could backport these
fixes to -stable after some more positive testing.

Is the system that was having these issues btw. running a preemptable kernel
or does it have multiple cores or hyperthreading?

Thanks,

My two ROSE-FPAC nodes have been running for 8 days and 12 hours without
disruption.

Tonight I noticed that "use" parameter was negative (-1) while remote node
station F8COJ-11 was not connected (restart = "no" and tf counting).

Later, F8COJ-11 node got connected again (restart = "yes") and "use" = 1.
Then "use"  returned to 0 after a few minutes.

This system is the one with SMP kernel and Voluntary Kernel Preemption (Desktop).

At the same times, on my second Linux system (with maxcpus=1 boot kernel parameter), use was 0 when not connected and it keeps displaying use=1 since ROSE neighbour F8COJ has been connected again.

However, both nodes are performing well and are able to route ROSE frames to F8COJ-11.
