This is how I could reproduce this bug:
(http://bugzilla.kernel.org/show_bug.cgi?id=4870)

- Configure the 1st kernel to take a kdump and run 4 instances of LTP on
it (I used `runltp -p -l logfile -t 12h -x 4)
- After a few hours, the 1st kernel crashes which results in the booting
of the 2nd kernel (the kernel which captures kdump). While this is
booting, mptbase driver fails during initialization leading to the panic
of the 2nd kernel.

The instructions to configure the 1st and the 2nd kernel to enable kdump
is found in Documentation/kdump/kdump.txt. I used the exact instructions
therein.

I am pasting the complete bug report from bugzilla here:

Software Environment:
Running 2.6.13-rc1 as the capture kernel.

Problem Description:

When the 2nd(capture) kernel boots (to capture the dump after the base
kernel
crashed), the Fusion MPT driver initialization cause a system panic.

Steps to reproduce:

- Configure the system for kdump
- Allow the base kernel to crash
- To capture the dump, the 2nd kernel boots and panics during the
inialization
phase of MPT driver.

<0>Kernel panic - not syncing: Fatal exception in interrupt
----------log end---------------

------- Additional Comment #1 From Vivek Goyal 2005-07-11 04:14 -------

This seems to be the typical case of driver hardening required for kdump
cases.
MPT driver does not seem to be equipped to receive interrupts from
device while
driver is initializing. This works fine if driver is built with
MPT_DEBUG_IRQ
defined.

Note: CCing to fastboot as this is related to kdump.

Regards,
Bharata.
