Found that it loses my nub-settings after every reboot, and misreports battery life quite drastically - kept getting my PNDs crashing due to dialogs warning me about the battery being about to fail, even though prior to launching the PND it was at 48%
Back to HF7 for me!
SuperZaxxon with old kernel is exactly the same as HF7B1 (except for some zenity scripts), so there shouldn't be any problems here...
That's odd, then - I assume that the superzaxxon-with-old kernel is the blue bootscreen and the new kernel is the green? I've been using the blue (which appeared after I chose to use the new kernel) which kept losing nub settings and losing nub configuration after a suspend. This one (old kernel) also did a proper power-save suspend which lost only a few percent of battery after being left overnight. After a reboot, I decided to go back to the old kernel (wrongly assuming I was in the new one) and had no option, so I chose to use the "new kernel" option again, in the hope that it might toggle the old one back in. I then got the green boot screen and the newer kernel. Things went rapidly downhill from there, so I'm going back to HF7 to get some stability.
The new kernel brings some astounding new features to the table, but it's nowhere near stable enough for day-to-day use - but I'm very glad to have had the chance to test it, and for that I'm truly grateful!
Edit: Just tested again - set the nubs as left/mousemove right/mousebuttons, then hit log-out/restart and it lost the nub settings going back to the defaults again. Definitely going back to HF7b1 now!
