Comment 13 for bug 34515

i am experiencing a similar (not sure if it's the same) problem on my notebook (HP dv8075EA). All 2.6.15 amd64 kernels (both generic and k8) that came up in dapper repository for the past 8 weeks immediately paniced on boot throwing tons of acpi errors, unless I defined "noapic" boot option. However, my self-baked 2.6.14 kernel from bpo sources works fine.

Please tell me if you need more info. Maybe I somehow could get a webcam and take a screenshot of the core dump if you think this would help.
