Description Matthew Garrett 2008-07-16 11:50:13 UTC
The PCI GART code has no suspend/resume support. As a consequence, on resume the
GART may be pointing to an incorrect location and significant memory corruption
may occur. The workaround in 2.6.26 is to add stub functions which simply reject
a suspend in this case. This patch is a backport from 2.6.26 to RHEL.
