2.5.74 released.

Actually, I've got another problem, too! Using certain DVDs, I'm unable to mount /dev/cdroms/cdrom1 (my DVD drive, /dev/dvd -> /dev/cdroms/cdrom1 for mplayer's benefit) on /mnt/dvd. I get loads of errors about ide-scsi and some data being discarded. I can't get rid of SCSI emulation as I need it for my CD writer. The only way I've found of fixing this is to turn off DMA by default; however, I'm not actually sure this fixes the problem, and I quite like DMA, keeps things going relatively quickly.

Any ideas on this one? Is it a known problem?

Cheers,

Rob

Does anybody know when nforce2's onboard NIC (emerge nforce-net) is going to work with the 2.5.x series (if ever)???...
Just wondering. I feel technologically excluded.

Right. That was unimpressive.

The kernel with O2 applied works fine, but is pretty much just as reported for O2 + granularity.

Right now I'm sitting in "vanilla" 2.5.74-mm1, just O1 (no granularity), and XMMS performance is a lot better than above. When browsing around in Nautilus (2 instances at once even!) XMMS doesn't lose a beat in the first 5 seconds as it does with O2. I zippily start a song, open Nautilus, browse a large dir, then go back to ~, and XMMS is fine. Certainly not the case with O2, which will lag a second or so.

However, X responsiveness is terrible. Even with just a Galeon window on a workspace (others in a different workspace), when I first start whipping the window around, my icons go missing immediately, and for a long time. After a while and/or I let go, everything seems to adjust and further movement draws the icons fine. Moving a window over another quickly, however, makes all hell break loose. The moving window is generally choppy, the underlying window gets a lot of fragments, and there's more fragments in the moving if it goes offscreen and comes back. Really cruddy. XMMS keeps up fine during all of this though.

Well, I hope this is somewhat helpful for Lovechild/Con/anyone. I'm in -mm1 right now, but I kept the kernel with O2 around in case someone wants more testing.

EDIT: Still a slight hiccup in XMMS performance when Galeon does a lot of rendering (say, going back to a large, graphical page) in the first couple seconds of XMMS play. Don't know if this is just the XMMS issue not being entirely gone, or because of the Gecko engine rendering being a hog, or some vile combination, or something else altogether.

robmoss2k: it's not just gnome-terminal, its all terminals.

Okay, gnome-terminal now works. Thanks guys! :-)

However, I still have a problem with any terminal other than vc/1. There's still no cursor. Is this a configuration problem, or a kernel problem? It just seems kinda weird that I get a cursor on the default terminal but nowhere else.

Also, I'm getting lots of really strange errors relating to my DVD drive. What's this "DMA problem" I keep hearing about? I can't find any reference to what it actually is, despite much trawling through the forums!!!

Cheers,

Rob

Okay, this is really weird.

When I have "Use PCI DMA by default when available" my DVD drive becomes utterly useless. Mount complains about a bad superblock when trying to mount either a DVD or a CD; mplayer complains with a DVD like this:

I'm getting the same results as everyone else with granularity, O2 patches. I've also set min_timeslice = max_timeslice = 10 (anyone know a good value for this? min_timeslice = 1 causes problems, like leaving zombie processes all over the place).

xmms skipping is about the same (no problems after a couple seconds). This could probably be solved by using a sound server like arts, but I'm not going to bother setting that up - a couple of blips is tolerable. Mouse jerkiness is basically gone, and windows move normally. All in all, the patches aren't perfect, but they're improving.

thubble: I found a while ago that a good way to beat the XMMS blues is to output using the crossfade plugin. That loads the next song while the current song nears completion (so it can start applying effects), so you don't get the weird chop on start of a new song. It essentially makes your playlist one big file. You can configure it so it sounds more or less like a normal output plugin.

I get weird window moving lag with -mm1+O2 and moving XMMS. It will keep up, but after a while the window will just get "behind" the mouse, and when i let go, it will finish up the moving it should have done. It's weird. Whipped the window around while it was playing and nothing happened. Let go and started moving it normally, and it immediately lagged behind. Didn't try anything with the timeslices, will do now.

Does anyone know why con's stuff isnt in www.kernel.org's people section? He is an "offcial" kernel hacker isnt he?

I've almost fixed my problem. Unfortunately, I'm left being unable to play DVDs. And still I have no cursor on vc/2 - vc/6, but I'm not that bothered about that as gnome-terminal works now.

It would appear that my DVD drive, which identifies itself as a SAMSUNG DVD-ROM SD-612 (Rev 0.1), won't work under the 2.5 kernel with DMA enabled, but will work under the 2.5 kernel without DMA enabled and will also work under the 2.4 kernel with or without DMA enabled.

Should I file this as a bug to lkml or wherever it is you send such things? Something has definitely broken between 2.4 and 2.5, but I don't know what I'm doing quite well enough yet to work out whether or not this one's already been discovered.

Hey guys...
Now do you all use ALSA for XMMS or OSS. It seems ALSA has trouble with scheduling (or whatever) because in XMMS an error msg about I/O comes up and a skip happens, yet in OSS emulation I don't get a skip or anything. Both tested when Galeon refreshes or does anything basically.

Another thing, is it possible to use ATAPI cdwriting with a cdrw/dvd combo?

Thanks.

Robmoss2k: Kernel.org's Bugzilla is where the 2.5 kernel bugs go. Perhaps you can find your problem already listed there?

Hmm, since 2.5.73 ALSA seems smooth in xmms now here.

That nvidia thing is quite worrying. I'll have to have a go and tell you what I get - I need to use the nvidia kernel module as well, and it works fine with 2.5.74-mm1. Fingers crossed...
