Summary: 2.6.16.16 and Pentium D dies at boot in ACPI Kernel Version: 2.6.16.16 Status: NEW Severity: blocking Owner: [EMAIL PROTECTED] Submitter: [EMAIL PROTECTED] Most recent kernel where this bug did not occur: Unclear (seems to work under knoppix) Distribution: Slackware Hardware Environment: Pendium D dual core, nvidia graphics, SATA drive Software Environment: gcc-4.1.0 I posted this to the linux-acpi list and was advised to file a bug report. Here's where I am with the problem up until now. Thanks for the reply, I've answered in context below.

With 2.6.16.16 things hang at boot time when ACPI is enabled (even > >when passing acip=ht at boot).

Yes, this is the last thing I see (unless I fool around with the ACPI boot parameters, where I don't even see this line). > Any chance you can capture the console output with "debug" > from the failure case? You mean pass debug as a boot flag?

I tried acpi=off and noapic and that worked.
