Bug 239215 – sys-kernel/hardened-sources-2.6.25-r7: cpqphp driver causes kernel panic or module segfaults when added.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description andrew.hampe 2008-10-01 03:52:54 UTC]

Enabling the cpqphp driver (Compaq Hot Plug PCI Controller Driver) compiled into the kernel and then booting the kernel on a COMPAQ ProLiant ML370 G2 Server causes a fault ending in a kernel panic. When compiled as a module, the driver will segfault when added (but does not result in a kernel panic).

Reproducible: Always

Steps to Reproduce:
1. Get your hands on a COMPAQ ProLiant ML370 G2
2. Compile the kernel with the cpqphp driver (Compaq Hot Plug PCI Controller Driver)
3. Boot the kernel

Actual Results:  
At boot with it compiled into the kernel, the kernel will hit an error initialization it and cause a kernel panic. With it compiled as a module, the system will boot, then during the boot the module will be attempted to be added into the kernel, and it will segfault, and the trace gets printed to the console, but the system continues booting.

Expected Results:  
At boot with it compiled into the kernel, the system should have booted without incident. The same goes for when the module gets added to the kernel.

The motherboard does have hot-plug PCI slots, two PCI 64-bit slots, one with the Smart Array 5i RAID PCI card installed, the second slot blank. I believe that this driver is meant or at least should support the slots/motherboard.

Snippet from console output when booting system with driver compiled as module (extra junk text is apparently due to the system not likeing that the console is set to the serial port)

Please also post your kernel config, thanks.

I have since changed my config no to include the driver to let it boot. I've reconfiugred the kernel again with the driver and I'm going to upload the new logs and config as soon as I get them.

What was the last kernel that worked (if any)?  Would it be possible for you to try with gentoo-sources-2.6.25-r9?  Could you also try hardened-sources-2.6.25-r7 again, but with all Grsec/PaX options disabled?

There have been issues in the past with PaX and some Compaq RAID controllers, but I believe those were cleared up.  Would like to narrow this down a bit though before getting upstream involved.

Re-open when willing to post requested information.
