Bug 89409

I'm posting this in response to Mark Linimon's call for reports of regressions in 6-STABLE wrt 5-STABLE (http://lists.freebsd.org/pipermail/freebsd-stable/2005-November/019730.html)

This may be a duplicate of PR 87568, but I wasn't sure, so I thought I'd open this.

I have a system which ran extremely reliably under RELENG_5 (from 5.3-RELEASE onwards). The machine suffers from frequent hard lockups when running a RELENG_6 kernel. The problem can be entirely worked around by disabling ACPI ("hint.acpi.0.disabled=1" in /boot/loader.conf). No such precaution was necessary with a RELENG_5 kernel.

The system is an AMD Athlon XP 2500+ processor on an Abit NF-7S v2 motherboard, with BIOS version "nVidia-nForce-6A61BA1BC-26". The system has a HighPoint Rocket RAID 1640 SATA card which I suspect (but have not proven) to be implicated in the problems - freezes appear to be related to disk activity.

I've tried building a kernel with GDB, INVARIENTS and WITNESS in an attempt to find out more, and not had any more success: the kernel still locks up, doesn't panic or output any more diagnostics when it does. The system will not break to the debugger when frozen.
