Intel 845pe chipset

[oakleys]

Is new hardware always such a pain in Linux?

I've installed Mandrake 9 (2.4.19-16) on a P4 2.4G/Intel mobo (chipset 845pe), and I'm getting a PCI conflict--from dmesg:

PCI: Device 00:1f.1 not available because of resource collisions

The information I've found so far leads me to believe that newer kernels have support for this chipset, but the details are "foggy." Apparently, without this device I don't have DMA. I had a similar problem not too long ago with a VIA chipset on a Redhat box, and dmesg produced an email address for a Czech driver guy (who promptly sent me a patch), but no such luck in Mandrake.

Is anyone here familiar with this kind of problem? I installed hdparm to test the drive parameters--low and behold the results sucked:

/dev/hda6:
Timing buffered disk reads: 64MB in 20.39 seconds = 3.14 MB/sec:eek:

Should I try a newer kernel? What would the new kernel break?

Thanks in advance!

Try to use hdparm -d1 /dev/hda

some my results without using hdparm settings :)
hdparm -tT /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.84 seconds =152.38 MB/sec
Timing buffered disk reads: 64 MB in 1.96 seconds = 32.65 MB/sec

hdparm -tT /dev/hdb
/dev/hdb:
Timing buffer-cache reads: 128 MB in 0.87 seconds =147.13 MB/sec
Timing buffered disk reads: 64 MB in 2.39 seconds = 26.78 MB/sec

Using 7200 rpm hd's and ata66 :)

And Mandrake kernel is quite new.

I get the same message as Oakleys in Mandrake 9.0. I have a Intel 845G chipset. I don't think it is recognized by the kernel either. I don't know what effect it has on hdparm.

I do know that hdparm will not work with any kernel 2.4.19 I have tried. Not Suse 8.1, not Mandrake, not Debian. Funny thing is that hdparm will work with 2.4.18 kernels. I boot with both 2.4.18 and 2.4.19 kernals in Debian and will get an error message with the 2.4.19 kernel. RH8.0 uses the 2.4.18 kernel and has no problems with hdparm.

It doesnt have anything to do with the chipset being too new, Ill tell you that, Im using the i850 with nary a queef of a problem.:)
