Default Bug#571761: linux-image-2.6.32-2-686: 2.6.32 required noapic on Acer Travelmate 430 where earlier kernels did not

Package: linux-2.6
Version: 2.6.32-8
Severity: important


With kernels up to 2.6.26 this ancient machine did not require any special kernel boot options, but with 2.6.32
I need to add noapic to the kernel command in grub.

If I do not add noapic the kernel gets as far as the pcmcia socket and gets through that completely, and then hangs
competely - nothing works.

Looking in the 2.6.26 kernel dmesg just after the initialisation of the pcmcia socket there were messages about
ACPI derived interrupts. So I thought trying noapic was worth trying noapic, and now 2.6.32 boots normally.

This suggests that something has changed in the APIC handling for the old chip in the 430, for the worse. Of course
now manual intervention is required to make this machine boot.

ACPI and APIC are two entirely different technologies, although they are
both involved in interrupt routing.

Please report this upstream at <http://bugzilla.debian.org> under
product 'Platform Specific/Hardware', component 'i386'. Attach the
kernel logs for 2.6.32 with and without 'noapic' to the bug report.

Sorry, I don't know how I came up with that URL... please use the bug
tracker at <https://bugzilla.kernel.org>! Then, let us know the bug
number so we can track it.

Once a job is fouled up, anything done to improve it makes it worse.

David, did you report this upstream?

Cheers,
Moritz

Hi David,

Yep, that sounds like a symptom of nothing good. I don't see any
relevant changes upstream, so I'll just ask:

- does trying a v3.0 or later kernel (e.g., from sid) help?
- if so, what is the earliest version after 2.6.32 you remember
that worked?
- if not:
- could you attach dmesg output from booting without
noapic (for example using netconsole to capture the output)?
- please report this upstream at http://bugzilla.kernel.org/,
product platform-specific, component i386.

Thanks for reporting and sorry for the trouble,
Jonathan
