I think it was never titan's intention to make our devices unbootable. The incidence is apparently unexpected, though it seems to be the first time to have situations like this.
I understand uboot is of much interest to devs and ppl who love tinkering with kernels and bootloaders. But as a non-power user, I am afraid I am far from being happy with it. Long before adopting the n900, I was using a zaurus loading an distro which also changed its bootloader to uboot, and then many users ran into trouble as that uboot was too difficult tame with and the ultimate solution is to wipe out everything and do a clean flash. Since then I have tried to stay away from it whenever there is a better (easier) alternative, like kexec.
My impression is that this incidence has more to do with uboot rather than the kernel itself. Or maybe I am mistaken.
Back to this, titan and matan, is there any more remedy work in progress? Yesterday matan offered a kernel which was supposed to be able to boot up the device, however it didn't work as booting still ended up in the forever "starting kernel".
I did enjoy my n900 overclocking. I would still use this kernel if I manage to get it booting again, yet I will do so only if it is just buggy but not unbootable. As regular users we do need some emergency plan when the worst scenario happens.
Now it's no use to point fingers and accuse and bash anyone and hurt our feelings. The most urgent issue is to fix booting.
