Here are some more data-points for the VT6102 network controller not working with a local IOAPIC. I have an Epox 8K9A3+ motherboard, with VIA KT400 chipset and a VT6102 network chip on-board. 00:00.0 Host bridge: VIA Technologies, Inc. VT8377 [KT400 AGP] Host Bridge 00:01.0 PCI bridge: VIA Technologies, Inc.

MGA G400 AGP (rev 82) In the following table, 'works' means the system works allright, and the VT6102 functions fine. (1) 2.5.68 + apm + local ioapic: boots & works (2) 2.5.68 + acpi + local ioapic: boots, doesn't work (3) 2.5.68 + acpi + no local ioapic: doesn't boot, hangs just after ide1 at 0x170-0x177,0x376 on irq 15 ^^^^^^^^^^^^^ it hangs just after this line. it would continue like this (with the working kernels): hde: host protected area => 1 hde: 156301488 sectors (80026 MB) w/8192KiB Cache, CHS=155061/16/63, UDMA(100) I'll attach the 2 dmesg outputs, one of (1) as dmesg_2568_apm_apic.txt and of on (2) as dmesg_2568_acpi_apic.txt. I've cc'ed Jeff and Alan because they seemed to be interested in this VT6102 problem. If there's any information anybody wants, lspci -xxxxx or whatever, just let me know.
