I just replaced the hard drive inside this computer two days ago and installed Slackware 9 on it. All the devices worked fine and there was no problem until I compiled a new kernel (2.4.22). Upon rebooting the new kernel, I would lose network support. I messed around with it for the better part of yesterday and in the end i gave up and installed a PCI card, which solved the problem. But last night I noticed when I tried to install cups that I had no USB support either. This problem never happened on my old installation, and I've tried using several different kernel versions...including the 2.4.20 source tree that had been there in the first place, and I tried reinstalling Slack once to the same effect.

All the modules load up fine, but the IRQ for my built-in NIC gets set to either 16 or 237...it's normally 11. All the problems seem to be revolving around the onboard components of my motherboard, and their IRQs. Any suggestions? dmesg brings up the following concerning the USB ports: (By the way, it's an Abit motherboard, the onboard NIC uses the via-rhine module)

did you try making your new kernel with make oldconfig and using a config file from the kernel that worked correctly?

No, sadly I haven't got any of my old kernel configurations around anymore. Lost a good deal of data on the old hard drive. But I remember pretty much every setting that I've ever changed, and even so I've played around with it quite a few times with several different kernel versions.

It seems like NOTHING integrated into my motherboard works, I just realized a few minutes ago that even the UDMA feature on my IDE controller is disabled and cannot be set with hdparm.

ok look in your /boot dir you will most likely find a config-ide-2.4.20 file which is I think the stock config file for the default kernel ( that is if you haven't deleted it heh). If that file is not there I could email you a copy of mine.

Yep, config-ide-2.4.20 is in /boot ...anything special I need to do with it? Never needed to in the past.

thanks a lot for the help

copy it to your 2.4.22 kernel's source directory as .config and then do a make oldconfig this will give your 2.4.22 kernel the same configuration as your original kernel that you said you had no problems with. you will only be prompted for changes that the new kernel has like new device drivers. in your kernel config steps make oldconfig would take the place of the make xconfig or make menuconfig step

Oh by the way if your motherboard has a via chipset and you intend to use usb you may have better luck with the ac series of kernel patches

Thanks again, I will give it a try tonight
