Roy, Two more ideas...
(1) By "going graphical" you mean that you enter runlevel5, right? You have the X Window System root screen plus other stuff, right? And a non-responsive keyboard and mouse, right? And CTRL-ALT-Fx does not give you a tty console, right? First debug... log in as root at tty1 in runlevel 3. Run X with no adornment. # X Try to get back to tty1 CTRL-ALT-F1 This will isolate the domain of the problems and whether they lie within the X Window System/Xserver itself, or with other desktop issues, X/Gnome/KDE session management etc. (2) ================ A follow on suggestion... poke around in /proc/interrupts, iomem, ioports and such. You may need to provide some PnP overrides using (yech) the isapnp utility. I've seen video rob the IRQ2 (cascade) for synch timing. The AHA-1520 could be inserting itself in somewhere in the IRQ priority.

I've got a 2940 around here somewhere, I just didn't want to waist it on a CD tower. ----- Original Message ----- From: "Marty Ferguson" <[EMAIL PROTECTED]> To: "Triangle Linux Users Group discussion list" <[EMAIL PROTECTED]> Sent: Thursday, April 22, 2004 10:40 AM Subject: RE: [TriLUG] Speaking of weird hardware problems > Roy, > > Did you try just swapping around PCI cards into different slots? > The enumeration of the IO space is kind of arbitrary.
