hi. i wonder if there are any potential OS corruption issues if attempting to install the official PR1.2 on top of PR1.1 IF the "Enhanced Linux Kernel for Power Users" packages have been installed.

the enhanced linux kernel packages is required for some applications (like Mobile hotspot) as it adds alot of functionallity like additional "File Systems" support, wifi features, overclocking and more (...apparantly it messes up the "touchscreen calibration application" though)

i would guess theres a big risk for incompatibility with installing PR1.2 on a kernel modded N900, but im too inexperienced to judge this.


now, would it be a good idea to uninstall the Enhanced Linux Kernel before attempting a PR1.2 upgrade?

ps. i ask this question in advance as a preventive measure. i know PR1.2 isnt released yet.

I haven't used this enhanced kernel but my intuition would be that nokia will update the kernel in 1.2, so anything using features from the custom kernel you're using that are not available in the new nokia kernel will stop working.

I suspect that a new "enhanced" kernel will be needed. But this is not an authoratative answer.

I believe that Titan himself is using the leaked firmware and says the enhanced kernel should be compatible with PR1.2. I haven't experienced any problems with the leaked firmware in conjunction with using the enhanced kernel.

I imagine there will be adjustments when the real stuff hits the streets, but I don't expect a big problem. All the signs point to blue skies and fair weather.

well pr1.2 replaces the kernel, so I suppose you have to reinstall your custom kernel after updating if you want it.The update should work regardless, afaict.

I'll be uninstalling Titan's kernel manually before update and then reapplying afterwards. It won't be much of a hassle and its better to be safe than sorry imho.

No, you do not need to uninstall the Enhanced kernel. As the leaked PR.1.2 are not OTA and you will need to flash the device manually it will not keep the kernel. Same as formating your hard drive.

You will when done need to install the Enhanced kernel again. I have not seen any report on problems with the LPR1.2 and the Enhanced kernel. Though some have reported problems with the LPR1.2. Though you might need a new volt setting.

The last upgrade of Enhanced Kernel killed my N900 running LPR 1.2 , it started crashing doing anything and then went into infinite reboot loop.

I had to flash it back with flasher 3.5

thanks for sharing your knowledge, experiences and opinions.

i concluded from the feedback that it should be pretty safe to keep the enhanced kernel while installing pr1.2

but maybe ill wait with installing it for a week anyway after its release and read more experiences, just to make sure everything is fully compatible

then you probably installed an recent experimental version from extras-devel
and not the stable one.

when PR1.2 comes out (next year?) I recommend to deinstall the kernel,
perform the OTA and reinstall it.

Not really on topic but:

On meego developer list was discussed that a kexec-cabaple kernel is needed to dual boot maemo/meego.
So I just *guess* that PR 1.2 will have at least that enhancement, it may be they will add some other options (hoping they listens for community needs on a such easy task).
