Problems with 3Ware Raid Controller 8006-2LP

[trendco]

Hi,

the last day's, i tested Proxmox-2, but i have some Problems.

My Hardware:

Mainboard: Z68A-GD65 (G3)
CPU: i5-2500T
RAM: 16GB
DVB-S: Mystique SaTiX-S2 Sky Xpress DUAL (PCI-E)
ISDN: AVM-B1 (PCI)
Raid: 3Ware-8006-2LP (PCI)

The Installation works good and the raid controller was detected correctly.
After that i ugrade the system with:

aptitude update
aptitude full-upgrade

uname -a

-> Linux proxmox 2.6.32-6-pve #1 SMP Mon Dec 19 10:15:23 CET 2011 x86_64 GNU/Linux

Now i installed a Windows-VM. I have already noted here, that everything is very slow and also in the vm the speed is not very fast.

On the console I noticed the following output:

irq 16: nobody cared (try booting with the "irqpoll" option")
handlers:
[<ffffffff81398050>] (usb_hcd_irq+0x0/0x90)
[<ffffffffa0025770>] (tw_interrupt+0x0/0x8a0 [3w_xxxx])
Disabling IRQ #16

Is there a problem with my raid-controller?


The next Problem:

I tried to boot with the option "intel_iommu=on", because i want to passthrough my DVB-Card to one Linux-VM. But then i enable the "intel_iommu=on" on boot, i permanently get the following errors on the console on each write operation:

.....
DMAR:[DMA Read] Request device [06:00.0] fault addr fffbb000
DMAR:[fault reason 06] PTE Read access is not set
DRHD: handling fault status reg 3
DMAR:[DMA Read] Request device [06:00.0] fault addr fffbe000
DMAR:[fault reason 06] PTE Read access is not set
DRHD: handling fault status reg 3
DMAR:[DMA Read] Request device [06:00.0] fault addr fffb4000
DMAR:[fault reason 06] PTE Read access is not set
...

What's the problem there?

The DMAR-Problem seems to be a known kernel problem:

https://bugzilla.redhat.com/show_bug.cgi?id=541397

There are many other requests in the internet about this.


I've tested a few other things:

"intel_iommu=on" with

- SSD-HardDrive to my onboard-Controller (Intel) in AHCI-Mode
- second onboard-Controller (Marvell) activated in IDE-Mode
=> no errors!



- SSD-HardDrive to my onboard-Controller (Intel) in AHCI-Mode
- second onboard-Controller (Marvell) activated in AHCI-Mode
=> DMAR-Errors!

I wanted to passthrough the second onboard controller to a VM


Any Ideas?

Is there is a new experimental kernel to test whether the problem is still there too?
