@all: use modprobe from now on (it's better/safer than insmod anyway), procedure:
Code:
modprobe ramzswap num_devices=1 disksize_kb=98304
swapon /dev/ramzswap0
swapoff /dev/mmcblk0p3
swapoff /dev/mmcblk1p2
(with second partition on SD being a swap partition)

EDIT: wl1251 also confirmed working (used fAircrack for checking)

EDIT 2: too early... after another reboot, modprobe with disksize_kb parameter supplied results ALWAYS in instant reboot. I've seen this behavior with colin.stephane's kp48 builds too. Some ideas where to check? I've sysklogd installed.

So, it works the first reboot after kernel flashing, but never after that. Every time a spontaneous reboot during which the custom kernel settings are not loaded.

EDIT 3: Confirmed. Compcache works only if:
- i freshly dpkg'd -i kernel, modules, and flasher (in that sequence, kernel-settings were retained from kp47)
AND
- performed a reboot.
And only then it works after this first reboot. From each consecutive reboot onwards. i observe the instant reboots after ramzswap0 initializing with disksize_kb. If i solely insert the module, no reboot occurs, but of course i cannot initialize it separately.
Mmmm, those reboots look like a clear symptom that the compcache modules are buggy.
Unfortunately I haven't setup scratchbox for N900 yet, so I can't help.

open filebox
go to /etc/multiboot.d and delete kernel power 48

So... Is Kernel-power v48 considered stable (in a kernel-power way) now? Are there any regressions or bugs?

Working stable for 12 hours so far although I haven't tried compcache yet.

I think v49 is pretty stable except compcache when disksize is defined to be so big that it does not use eMMC swap (mmcblk0p3) disk at all.

This is known issue, which was noticed in "COMPCACHE on power-kernel" thread. See this post. It is good to read the whole tread, if interested in about this nice feature.

I hope freemangordon has time to look this issue, because at the beginning compcache is fast and smooth until after some time system start to become unresponsive.

I did try again several disksizes and system settings with v49, but always unresponsiveness came after some usage. It would be a nice addon for N900 to get compacache running smooth.

copy that!
but only on one of my two N900s
unfortunately the primary one
guess i will switch & reflash the faulty one & see if it is SW (PK V48) or HW related (i.e. reinstall all the other SWs except PK V48)

I'm using it right now with disksize_kb=131072 with no issues at all, and no slowness for now.
Unfortunately, this being compcache 0.6.2 means that ramzswap statistics are accessible only from ioctl, so having rzscontrol is a must for debugging and checking its behavior.

EDIT: I have built rzscontrol in my N810 scratchbox, works fine, but the ramzswap module has been built without stats support, so it is useless.
@pali: could you build the module with stats enabled (define CONFIG_RAMZSWAP_STATS), please?

EDIT2: And could you apply the changes I suggested in the compcache thread? they'll increase the memory efficiency.
I have increased the ramzswap size to 192 MB and no stability problems so far, although I have hit a funny memory management problem when applying memory pressure: ramzswap usage has grown to 168 MB, swap partition remains at 0, and the cpu is pegged because the free memory goes up and down like a roller coaster against the used memory. I guess this is some kernel parameter configuration issue that can be easily fixed with a script "a la swapolube".
