Bug#629865: xen-linux-system-2.6.26-2-xen-amd64 causes system crash when using aacraid driver
Does this message mean Adaptec drivers are one big miserable piece of crap and can't be used on virtualized platforms? Does this mean RAID hardware products supplied by Adaptec / PMC are faulty and won't work on any Linux virtual platform at all?
I'm just trying to bring this to attention of PMC sales and clarify this moment because we've recently purchased such adapters and getting absolutely similar errors:
PCI-DMA: Out of SW-IOMMU space for 65536 bytes at device 0000:04:00.0
