I am trying to upgrade my laptop from 7.2 to 7.3. I used the default upgrade in YAST2 and things seemed to go as planned. However, when I try to start KDE 2.2, the startup hangs. The console shows the message 'spurious 8259A interrupt:IRQ7', and the cap=lock and scroll-lock indicator lights flash on and off. This continues 'forever' (I actually let it go all day today as I had to go to work!) The computer is completely locked, and I can't get into a text mode terminal or reboot. The only way to get out is to turn the computer off and endure the fsck process on the next boot. I also tried GNOME. This actually loaded and seemed to work ok for a while, but within a few minutes exactly the same happened. The computer seems stable in text mode if I don't get into a window environment. The above problems are using the stock 2.4.10 kernel. I also tried going back to the 2.4.5 kernel which I've been using in 7.2. This kernel is patched for win4linux. With the 2.4.5 kernel, KDE works fine. However the pcmcia system doesn't work, so I can't get any network connection. The network (and modem) cards had worked fine with this kernel in version 7.2. At this point I would really like to have a stable window environment with network support. I'm not particular about which kernel! Any suggestions greatly appreciated! Bernie w1az@arrl.net p.s. This is the second try. II don't think the previous message made it to the list, but if this is a duplicate, my apology.
