This changes the system resource assignments to ensure that the issue does not occur.
If this workaround fails:
• Add the kernel parameter acpi=noirq to the kernel command line to prevent the linux kernel from using the
I/O APICs.
For PowerEdge M805 and M905:
• Add the kernel parameter acpi=noirq to the kernel command line to prevent the linux kernel from using the
I/O APICs.
This issue will be fixed in a future BIOS update for the respective PowerEdge systems.
Cause This issue occurs because the Linux kernel changes the memory address assignments of certain add-on PCI
devices such that they overlap the second I/O Advanced Programmable Interrupt Controller (APIC) in the
system.
