ALI15X3: IDE controller on PCI bus 00 dev 78 PCI: No IRQ known for interrupt pin A of device 00:0f.0. Please try using pci=biosirq. ALI15X3: chipset revision 195 ALI15X3: not 100% native mode: will probe irqs laterWith a little patch this problem goes away and DMA seems to work. Hard drive speed is doubled according to hdparm.
Note: this problem is solved as of 2.4.20-ac2 according to Michael Leuchtenburg.
[root@amelia src]# hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 64 MB in 3.78 seconds = 16.93 MB/secNote that this bug makes it not possible to install redhat 7.x in a straightforward manner. I installed the hard drive on a physically different machine.
Georges Roux notes that using the kernel parameter:
linux ide0=ata66 ide1=ata66will bypass this problem with redhat-7.3 (kernel 2.4.18).
Roland Pabel has created some bootable SUSE-8.0 images to get around this.
In general, the laptop seems excellent. It is very difficult (and maybe impossible) to find a more adaptable, small, long battery-life laptop.
