I emailed about this earlier and here's some new info: the crash occurs
when ACPI is turned off. It appears that your driver is expecting
information from ACPI and if it doesn't get it, it will crash. (This has
been posted as bug http://bugzilla.kernel.org/show_bug.cgi?id=12733)
On a system with a Supermicro X7DWN+ with ACPI turned off, and an
LSI22320SE card installed, the mptdriver will crash. Here is the
relevant log:
This could very easily be a motherboard bug. Many newer motherboards are
NOT tested properly with ACPI disabled. Your case could easily be due to
the board's interrupt routing for certain slots/devices being messed up
when ACPI is not in use. For this reason it's generally not a good idea
to try to disable ACPI these days.
