Reasons for switching from 2.4 to 2.6?

err, couldn't we already do that with cdrecord 2.x? Or did that just move the emulation form the kernel to the application? Anyway, my 8x burner burns at 8x w/ >95% buffer with emulation.

let's just say it like this:

2.4 + cdrecord 2 = coaster creator.
2.6 + cdrecord 2 = joy.

Jens Axboe explained how this stuff worked at Linux Forums sadly his slides are in Danish - I'll see if I can get them translated for you.

Hmm....I started running 2.6.0-test8

The special stuff on my system:

Tyan Tiger MP
Dual 1700+
D-Link 54mbps wireless card (atheros chipset/madwifi drivers)
Radeon 8500 (fglrx)
IDE Zip drive
other normal stuff...

My current take is that 2.4.20-gentoo-r7 is more stable than the 2.6 series.
Since running 2.6.0-test8 and better for a couple of weeks I've had something like 5 lockups.

Problems:
test7 - accessing IDE zip drive locked machine hard.

3 video lockups so far, all during play of NWN. I ssh'd in and saw a kernel vm error associated with agp accesses. I also play UrT (quake3 mod) that might help push the error.

Hard lock just now...I was copying about 50G of data from one drive to another, running an mp3 encode on some files and scping several hundred megs to another machine.

I had another lock while also doing some network stuff.

The network drivers are beta, so I'm not surprised, but I'm not exactly happy about the video locks.

But I do have to admit, this new kernel is damn responsive. My X starts up truly instantanously with everything initialized, even mozilla, desktop switching is way snappy, I'm very impressed.

Ugh, I take that back, nwn just locked up the video again on me, I'll drop back again for a while....

i've quite a fast system: amd 2000xp / 768 MB DDR / Asus Ti4600 gforce4 128MB... and i'm running on fluxbox, currently got test8-mm1 but my x window does not come into life instantanously, like i'd want it. ok. i still takes under 10s and it's of course no problem to wait some seconds, but i've not made out any speedup since i switched from gaming-r5 to test8-mm1 concerning starting up applications. it is definitly more responsive, i can tell, but not necessarily faster.

i wonder if anyone of you had some lockups with -O3 optimization. i've decided to switch to -O2 for stability, even i havent tried -O3 with 2.6. i'll give -O2 some time for i havent recompiled everything important yet. after that i'm considering switching back to -O3 to check if my lockups came from the gaming-r5, the -O3 or maybe my hardware.

But the 2.6 kernel doesn't seem to be in portage? Where can i download eg gentoo-sources?

One of the reasons you won't see as much speed improvement with the 2.6 kernel from the gaming sources is that the gaming sources include a number of the 2.5/2.6 patches that improved performance and hardware support. So a 2.6 kernel will have a complete set of improvements as apposed to a 2.4 patched with some of the improvements.

P.S. I name my kernels with version number and tag on a {.a, .b, .c} etc. for each new compile.

i've quite some problems with burning on the fly. i've already wrecked some cdr's using xcdroast and not managed to successfully burn a single cdr. buffer jumps around like wild and i've got quite a good burner, aka plextor. i'm not that convinced of 2.6 by now. i'm currently using test9.

speed, savage hauls some serious butt versus the windows version.

I would have to say all the native Linux games versus their windows counterparts are alot faster in the 2.6 kernel due to the multitasking abilities.

I have been on test9 and loving it.

JUST MAKE SURE YOU DIDN'T USE GENKERNEL TO BUILD YOUR 2.4 KERNEL!!!

For one thing, like everyone said, SPEED! I actually had to turn down my mouse accel - which I never do!

For another thing, it has a whole lot more hardware natively supported, like my intel i815's drm patch, and so on. It's menuconfig is better looking, too.

BTW, what's that about BIO? I was using scsi emulation upto now!

Can someone tell me what I need to do to enable it?

And one more question, what's the sys filesystem there for, anyway?

update on cd burning. it seems my burner is the problem, or my firmware. i updated the firmware (is there a way to update your firmware in linux?). i had a strang message in xcdroast, concerning my ASUS DVD. it says something about a corrupt or wrong firmware. i updated my firmware and now everything seems fine, but i havent had those problems with scsi-ide.

Probably just a tiny incompatibility that sneaked in.

it was said that there's a supermount patch for 2.6 available. i've emerged mm-sources-2.6.0-beta9-r2 now, but i can't find supermount anywhere! has it be to patched it manually and if yes, how do i do that? or are there any other 2.6 sources that i may use?

Hi I'm runing 2.4.20-gentoo-r8 kernel and would also like to try the 2.6.0-mm-source kernel. If I understand corectly, I have to do the same as with instalation of the first kernel. After I have compiled the new kernel (with new name) l have to copy it to /boot and edit lilo.

My question is what do I have to do with nvidia drivers, someone mentioned
