The critical difference between my kernel and the precompiled kernel appears to be that the precompiled kernel has ACPI. Adding an acpi=off parameter to the kernel boot string appears to fix it.
My chipset is an old AMD-751 and AMD-756, which claims to support ACPI though I'd never enabled it before. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
