Running 2.6.12 on AMD Opteron on an Arima HDAMA board with a 3ware
8506 card installed and got the following in the log:
Jun 25 15:56:34 [kernel] [53161.700276] PCI-DMA: Out of IOMMU space
for 65536 bytes at device 0000:03:01.0
Jun 25 15:56:34 [kernel] [53161.700279] 3w-xxxx:
tw_map_scsi_sg_data(): pci_map_sg() failed.
Jun 25 15:56:34 [kernel] [53161.700332] SCSI error : <0 0 0 0> return
code = 0x70000
Jun 25 15:56:34 [kernel] [53161.700334] end_request: I/O error, dev
sda, sector 51296795
This error doesn't seem to be mentioned much in this space. Should it
be taken at face value? Is it something simple like IOMMU should be
set to a higher value in the HDAMA bios? A kernel bug? Or could it
actually be bad physical memory or even a bad card?
Does it mean the data integrity on the affected hard drive is compromised?
