Yep, it fails later but it doesn't boot from IDE. The SCSI disk is recognized correctly and the system is on the SCSI drive. The IDE disks only contain data. It fails later that is right but it still works after failure. Making IDE work was easy. A friend soldered the connectors and then I passed "ide0=ide0=0x1f0,0x3f6,14" as kernel parameter to make channel 0 work. Later on after, discovering what was wrong with 2.6 kernels, I enabled the correct interrupt in the appropriate table in prep_pci.c. > > I posted a message to linux-scsi describing this problem.

I hope there will be some input from the scsi list. As said above, it does really work although I have to admit there is a problem with PCI or IRQ handling in general. You can also see in my log that one of the ethernet devices has problems every now and then. All in all it is sort of functional. You can also try to remove every additional PCI device except the gfx card and see what happens. I had to remove an additional SCSI host controller in order to avoid problems with other PCI devices (mostly it was one of the ethernet devices which lost an interrupt). But I share your thoughts that there is something wrong with the sym2 driver. > > > >How does your boot.log looks like? > > > > Attached it. > > Note that I use a Matrox MilleniumII gfx card and XFree4 runs fine > > (without any crash) since I got a 2.6 kernel running (although I am not > > using XFree because I use the Powerstack as a router/server which has no > > Monitor). > > Yeah - I search so many times for a Millenium card on eBay.
