Summary: PCI0680 can't work reliably in UDMA mode over 33
Product: IO/Storage
Version: 2.5
Kernel Version: 4.8.0-27-generic #29-Ubuntu SMP Thu Oct 20 21:03:13
UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: IDE
Assignee: io_ide@kernel-bugs.osdl.org
Reporter: ilario.gottardello@gmail.com
Regression: No
Subsituting an HPT366 IDE controller with a Silicon Image, Inc. PCI0680 Ultra
ATA-133 Host Controller (rev 02) (so same pci slot / cables / hard drives), it
immediately fails to read data from the disks, slowing down the link to
UDMA/33.
