Hello All,
For the last couple of months (since at least 2.6.35 somewhere) I have
been seeing
"
....
[698612.423825] Device 0000:0b:00.0 unmapping: pfn ffc74-ffc74
[698612.423831] Device 0000:0b:00.0 unmapping: pfn ff96d-ff96d
[698612.639262] Device 0000:0b:00.0 unmapping: pfn ffc74-ffc74
[698612.639269] Device 0000:0b:00.0 unmapping: pfn ff96d-ff96d
....
"
in my dmesg output.
"
lspci -s 0000:0b:00.0
0b:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709
Gigabit Ethernet (rev 20)
"
The bnx2 driver is loaded on my system. I am presently on 2.6.36-rc3
kernels but like I mentioned I have been seeing this for a while.
Any ideas? I would rather not have this endless message in my kernel
logs.
Thanks,

drivers/pci/intel-iommu.c line 2737
pr_debug("Device %s unmapping: pfn %lx-%lx\n",
pci_name(pdev), start_pfn, last_pfn);
So you asked/activated some debugging, because pr_debug() is not default
enabled...

It's not the bnx2 driver, it's the intel-iommu driver.
This is coming from a pr_debug() statement, so turn off
CONFIG_PCI_DEBUG to get rid of the "DEBUG" define that
gets added to the kernel build command line which causes
that line to print the message unconditionally.
