OZ 3.3.6pre1 Suspend Problem on SL5500

[tsm]

Hi all.
I\'m a SL-5500 user, and i\'m using oz 3.3.6pre1 since the release.
I realy love OZ, but this problem is just anoying me.
When I came back from a suspend, the touchscreen is not working. I can navigate using the buttons, but the touchscreen is dead. Just a reboot solve the problem.
Any tips here?

Thanks for the help.

Have you removed the current one and installed the hotplug ipk from OZ3.2 stable?

Yes. I did installed hotplug_2002_08_26-8_arm.ipk in place of the original hotplug from 3.3.6.
Touchscreen simple don\'t work after waking from a suspend.

If you, or anyone here give me some tips I can try to solve the problem by my self, but I really don\'t know how this thing work and how suspend is related to the LCD touchscreen.

It is just like to lose you mouse after suspending your notebook and having to reboot it. Maybe there is a module to reload or a service to restart? Sorry, but I really don\'t know. I\'m just speculating here.

Nobody have ever seen this problem before?

Sorry for my english, I\'m not very good on it.

Thanks again.

I (and others have) had this problem but can\'t for the life of me remember how to fix it.

That said it should already be on the forum somewhere, what did search turn up?

I just did a quick search and couldn\'t find much, it may have been on the devnet.

I don\'t know. Have you tried a hard reset (just on the off chance it might work).

Can anyone else remember what the fix was for the touchscreen not working after suspending (I could swear it was to replace the hotplug ipk, but I thought that was for OZ3.3.5, not 3.3.6preX). If you get bored you could try reinstalling the correct version of hotplug from the 3.3.6pre1 feed.

Before posting I did a search too without sucess.
I have tried a hard reset, but didn\'t work.

Just now, i have unppluged my SD card and rebooted, it just worked. The touchscreen is working again.

I own a SanDisk 256MB SD card formated with ext2 (1 partition only) and it works just fine. Maybe there is some issue with SD modules or kernel or even again with hotplug (insert and unpplug cards is working very fine),

Review the tests I did:
- No touchscreen after a suspend
- Changed hotplug to the one from OZ 3.2 - no touchscreen
- Hard Reset - no touchscreen
- Boot without SD, then suspend - Touchscreen working
- Boot with SD, then suspend without it - Touchscreen not working
- Boot without SD, then insert it and suspend - Touchscreen not working
- Boot without SD, then insert it, play some games, then remove it using cardmon - Touchscreen working.
- Boot with SD, then try to remove it using cardmon: SD/MMC can\'t be removed!, then remove it from slot and suspend - Touchscreen not working

It seems that the problem is related to SD.
Any ideas?

I can\'t help you with this as I only have an MMC card.

Have you searched the mailing list?

Have you searched the mailing list?

Witch mailing list?
I have searched google a lot, and also here at ZUG.
I couldn\'t find any mail list at OZ site.
Can you point me to them?

I\'m thinking about geting the OE build system and sources to learn more about the system and try to fix this thing.
If there is any source of info on how the suspend work and how it integrates with the SD/MMC module it would be usefull to.
I\'m not a developer, but have some basic knowlege on C and some shell and perl scripts for sysadmin and customization. I will try to find a way out.

If you find or recive any info, please let me know.

Thanks

I use a sandisk 256mb sd-card .ext2 format with no problems on sharp rom or oz, but I have had to hard reset to fix touchscreen on oz 1 time.

Ok. I have not solved the problem, but i have a dirty workaround.

The problem is not SD, but my Wireless Card. If I eject it (with cardmon or simply unpluggin the card), suspend works without any problems.
Anyway, hotplug is the one from OZ 3.2, so I don\'t know if the OZ 3.3.6 hotplug has the same efect.

I have unppluged my wi-fi card to play some GB roms in my CF card and suspended Z. When I came back, touchscreen was working again. So i tested the wi-fi card.

Maybe next weekend I try to modify suspend scripts (?) to eject the card automatically, so I won\'t have to do this by hand every time.
Any coments? Any ideas?

Thanks again for your atention.
