Anyone else noticing ramzswap taking a nosedive from time to time?

lma | # 432 | 2011-07-13, 14:03 | Report

Not here (current uptime 69 days), but my setup may be different:

/proc/version:

Linux version 2.6.21-omap1 (miguel@linux) (gcc version 3.4.4 (release) (CodeSourcery ARM 2005q3-2)) #23 PREEMPT Sun Jan 16 13:38:22 CET 2011

(I know I should upgrade at some point) I think my current modules were hand-built from the latest compcache + maacruz's patches, but I can't find the build dir in my scratchbox right now. In any case, they're:

I have, and I have disabled it from starting up.

I noticed that when running two or more large apps (i.e. canola, navit), while ramzswap was running, would see my n810 "bog-down" (get real slow) for several seconds. When I disabled ramzswap ("swapoff /dev/ramzswap0"), removed the kernel module ("rmmod ramzswap") and went back to using a dedicated partition for my swap space, things would run much more smoothly and consistently, even if slightly slower.

What do you mean by "nosedive"?
Slowdown?

Sorry, either crash or otherwise shut down.

I have sadly never caught it in the act, because my best indicator is that ASUI stops showing the orange long press indicator on the memory use readout.

Well, I just installed (or think I did) the CSSU and Diablo-Turbo.

When I enter , however, I get:

Was I supposed to actually get "noname" as part of the string (and not get "Nokia-N800-43-7"), or did I get to the new Diablo Turbo correctly?

The 43-7 in that string seems a bit surprising since "About Product" from the control panel says "Version: 5.2010.33-1". (5.2008.43-7 was the code for my pre-CSSU OS.)

The only oddity during installation was that I did not get an error about sysvinit on the main installation; I went ahead anyway and entered , which did produce an error (which I ignored).

Did you download all debs, including "Previous release" ones?

Sounds like you were using ramzswap only. That won't hold much data (especially with the default config) and so you can run out of virtual memory much earlier, causing the symptoms you describe. Canola and navit (is that stable these days btw?) probably store non-compressible data (images/sounds) which makes the situation worse.

IMO you really do need the swap file as well, just with a lower priority so that the compcache swap is used first while it has any space left.

Does it happen often enough that running syslogd would be useful?

Good guess! Nope, I omitted those. I'll do it again tomorrow with those included. Thanks!
