Asus CUV4X-DLS apic fun (pre8/ac22)
With apic enabled on this board, some normal amount of disk access (including building a kernel) is successful. However, irqs are messed up. The eepro100 module for the onboard 82559 nic loads, but prints this after the revision history: PCI: No IRQ known for interrupt pin A of device 00:07.0. Probably buggy MP table. Also, when booting with apic, I get this (with both MP Spec 1.1 and 1.4) ... IO APIC version: 0011 WARNING: unexpected IO-APIC, please mail to [EMAIL PROTECTED] dmesg for both MP Spec 1.1 and 1.4 for ac8 boot are attached (it looks like there's one more irq in one of the modes, eepro has same error on both). ac22 has the same io-apic warning and eepro100 load-time messages. with noapic, dmesg includes this nugget of information after eepro100 revision history and before all the usual diagnostic s and self-tests: PCI: Enabling device 00:07.0 (0014 ->0017) PCI: Assigned IRQ 5 for device 00:07.0 This is all with the latest bios vdls1010. The changelog lists "Support Solaris 8.0 dual processor environment" so I thought it was worth a shot, but doesn't seem to fix the problem. On Wed, 27 Jun 2001, J.

It seems the kernel (2.4.6-pre8) has decided to use 4MB of swap in addition to the 200+MB of physical ram. I guess this is another weird system situation that the vm could be optimized for, but at the expense of good performance for the other 99% of the world.
