Subject: swiotlb default size (64 MB) too small?
Date: Tue, 20 Jan 2009 21:10:48 +0100	[thread overview]
Message-ID: <49762FC8.7000208@s5r6.in-berlin.de> (raw)

Hi,

somebody reported frequent "Out of SW-IOMMU space" failures when copying
between a FireWire and a USB disk.  swiotlb=512M on the kernel command
line fixes it for him. https://bugzilla.redhat.com/show_bug.cgi?id=478567

Should the default be raised?
