N900: eMMC swap seems broken with kernel 6.6

[Arno1103]

N900 is really slow and buggy but randomly when i use 6.6 kernel (screen freeze on boot, 25 sec to launch some apps, mix of two apps shown in the same window, H-D not responsive enough).

It sometimes works fine for several minutes.

Benchmarking SD card and eMMC doesn't show any difference compared to 6.1 ATM.
(need more investigation)

Tweaking or reverting vm parameters has no effect. (excepting swappiness=0...)

But the use of SD card swap completely solves the issue so something seems broken with eMMC swap.

There is absolutely no eMMC swap issue using kernel 6.1 and the exact same Leste install.

I didn't notice any relevant error in logs ATM.
