2.6.4_rc2-love1 aka "Spread 'Em"

[d-fens]

sorry it wasn't udma , just dma under Device Drivers | ATA/ATAPI/MFM/RLL support
[*] Generic PCI bus-master DMA support
[*] Use PCI DMA by default when available

alsa: make sure you compiled the drivers as modules
pppoed: you should provide more specific information like what dmesg says about it or the output of lsmod

After removing this line it works for me

Yeah, works for me as well. Thanks!

hmm I have the same problem:

But if I remove the line

Code: Select all

proc_alloc_map); 

I got this compile error

Code: Select all

Whats wrong?

[bssteph]

You removed the wrong line. You should remove the line with the - in front of it, that is,

Code: Select all

BUG_ON(de->subdir);

On a side note: I've disabled preemtible kernel now and it really makes a difference on my system. Before it seemed rather sluggish when there was heavy hard-drive activity, sometimes even disallowing me too take any action, now my box seems to respond faster when wanting to do multi-tasking. I've read some other reports about slowness, so I thought I'd just mention it

What?! So I should disable preëmptible kernel? People always told me this was the major advantage of the 2.6 kernel tree; it should speed things up. So should I disable this, or not?

Besides, what other things should I enable in my kernel to get more speed with love-sources?

ahh ok, thx
