We use the fixmap for accessing pci config space in pci_mmcfg_read/write().
The problem is in pci_exp_set_dev_base(). It is caching a last

pci_mmcfg_read/write() is used.
Good catch. I already had another report of mmconfig corruption on i386,
but didn't have time to look at it yet.
Will be definitely stable material once it hit mainline.
Indeed.
If I found this in mainline, should I send something like a reminder
email with patch to you, Greg?
I have it already queued for both.
Oh, thanks.
