Sleep is a GoodThing. ;) The lpt is disabled and no support is compiled in. Before it's disabling, it is changed to "normal" mode, no ECP or EPP. Now that I'm awake, the problem I had was related to installing a new Adaptec 2940UW (1.5 years ago). Once installed, the system started generating stray IRQ7's and would panic. Swapped _everything_ out and disabling unused devices did in visual userconfig did nothing to help. Finally a BIOS update fixed the problem. >It's a hardware-ism. IRQ 7 is the generic junk IRQ. Why would changing to an elf kernel "fix" the strays? Nothing else has changed since the kernel went from aout -> elf. If it were a hardware-ism, as you say, this change should do nothing to eliminate the strays. Unless the new elf kernel ignores stray IRQ7's, because there are no drivers using that interrupt. The board is an older Asus TP4N using the FX chipset. Must be a common issue. I'll try a BIOS update and see if the old kernel still does this.
