And even stranger, now that I did not enable the printk it happened again. It
was sleeping, I touched the pad, power led came on, but screen backlight did
not, and it does not respond to keys or touch anymore. Also, it does not go
back to sleep according to the power led, so it indeed is frozen I'd say.
Mysterious.

If you could use 'diff -u origfile newfile> output.patch' from the

After that, in Etoys playback sounds a bit worse, but it's still
okay (hard to tell actually). And no freeze after suspend,
playing just resumes. So it would be a good idea to use that ALSA
plugin for Squeak in general, me thinks.
Could we get a squeak/etoys package with a fixed alsa-plugin ASAP,
please?
Someone would need to rebuild Fedora's squeak-vm-3.10-5 package with
Derek's patched sqUnixSoundALSA.c file (attached to the forwarded msg
below). The etoys package is unaffected.
I'm happy to apply a patch to the etoys package in Fedora if someone
can provide me a patch rather than a complete new source file.

Chris mentioned 3.10-5 and I do most my development on 3.11.3 so I diff'ed between them.

Re: F11-for-XO1.5 Release 10.1.1 Release Candidate 2
Hi, Bert and Derek. Derek just send me the combined version. I tested playback and recording on the XO 1.5 and it was perfect. Hooray! I did NOT test to verify that it survives suspect resume, as Derek's previous version did. Hopefully someone else has verified that. It sounds as though this fixed version of the ALSA plugin will get into the XO Squeak VM package. In that case, should I omit it from the next version of Scratch? (A new version of XO Scratch is coming soon to include the Lego WeDo plugin which Derek just finished.) Many thanks to Derek and Sayamindu for their hard work. -- John On Jun 14, 2010, at 7:08 AM, Bert Freudenberg wrote: > > On 14.06.2010, at 13:01, John Maloney wrote: > >> Hi, Bert. >> >> Re: >>> Tried sound playback in Scratch, it's choppy, many clicks to hear. >>> Suspended fine, resumed playing sound.

The sources for the current Fedora package. A source rpm has a tarball of the sources, and optionally a series of patch files relative to that "upstream" tarball. Not sure where to find those sources though, I'm not too familiar with Fedora procedures. - Bert - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hi, Bert. Re: > Tried sound playback in Scratch, it's choppy, many clicks to hear. > Suspended fine, resumed playing sound. Recording does not freeze the > activity, but has bad quality. Derek says that the recorded sound is actually okay if you export it and play it with a good sound player. Does that fit with your experience? The choppy sound in Scratch is known; the fact that it works in EToys makes me think that Scratch would work, too, with the right buffer size and sampling rate. I'll try a few variations... -- John ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I ask because I suspect a kernel panic and a serial port is a practical way to obtain more problem data.

See reproduction >instructions in the ticket. Installed on my 1.5 after updating the firmware to q3a39. Typing "boot" in OFW right after "fs-update" froze the machine. Powered off (long-press on power button) and booted. Let it sit idle for a while in the first-time Sugar screen (name dialog) -> machine froze. Powered off again, booted. Entered name right away, works. Tried sound playback in Scratch, it's choppy, many clicks to hear. Suspended fine, resumed playing sound. Recording does not freeze the activity, but has bad quality. Tried sound playback in Etoys, works fine, no clicks. Suspending with sound playing freezes the activity. Recording still freezes it too. (Both is unsurprising, fix not deployed yet) Copied ~olpc/Activities/Sratch.activity/vm-sound-ALSA plugin to /usr/lib/squeak/3.10-5/. After that, in Etoys playback sounds a bit worse, but it's still okay (hard to tell actually). And no freeze after suspend, playing just resumes. So it would be a good idea to use that ALSA plugin for Squeak in general, me thinks. However, after letting the machine sit idle for a while (even just after booting, still in the Sugar home screen), the whole machine froze. Power LED was still on. Had to power-cycle.

You must be working late ;-> At this stage the only difference between os203 and os126 looks like some newer f11 packages, correct? They both work fine (clean installed one and olpc-update the other) and Record-81 is a BIG improvement. Syncing is almost perfect (in my finger snap test :) up to a minute that I tested, operation is snappy, while image display while recording is pretty smooth. However, besides the annoying 5sec silent audio added in the beginning of audio recordings that Mikus described and persists, there is still an old nasty one with data-loss potential. In short trying to record a clip after you recored, played and deleted one, quits the application.
