I have a UP system with Via kt266a chipset. When I enable APIC in the BIOS and in Linux, the system boots mostly normally, but I get a fairly constant stream of APIC error on CPU0: 02(02) with a smattering of other numeric codes from time to time. Most things still work, but there are a number of oddities and instabilities, most notably my integrated uhci USB controllers give usb bulk-msg timeouts on every device. This happens with 2.4.20 vanilla, 2.4.21-pre4-ac6, Debian's 2.4.18-bf24 and every other 2.4 series kernel I've tried... can somebody point me at a faq/patch/person to help get me started resolving this issue ? Thanks in advance. -- Josh Litherland (fauxpas@temp123.org)
