Subject: Some problems with HP DL380 G8 BIOS and SLES11 SP3

Hello!

Running the current SLES11 SP3 kernel on a HP DL380 G8 server, there are some kernel messages that indicate a bug either in the kernel or in the HP BIOS. Maybe someone can explain, so I can try to get it fixed whatever party broke it...

Linux kernel is "3.0.101-0.35-default (geeko@...ldhost) (gcc version 4.3.4 [gcc-4_3-branch revision 152973]" (latest).
HP server is "HP ProLiant DL380p Gen8, BIOS P70 02/10/2014" (latest)

During ACPI init I see:
