Summary: pata_via: crash with VT6415 controller
Product: SCSI Drivers
Version: 2.5
Kernel Version: 3.0 and above
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No

Original Debian bug report http://bugs.debian.org/679039 has some further information.

Hardware is an ASUS M4A88TD-M/USB3 EVO motherboard with an apparently rare on-board VIA VT6415 PATA controller. I have one device linked to this controller, a LITE-ON DVDRW SOHW-1693S. CPU is a quad-core Phenom II.

Shortly after the pata_via module loads, the system hangs completely (no SysReq, no keyboard LEDs) with probability ~ 0.9. The crash is prevented with libata dma=1. Disabling the VIA option ROM makes no difference. The BIOS is the latest available version.

In Debian 3.6.33 and earlier kernels, I believe a different driver was used that did not crash. I could boot to confirm this.

The PCI device is:

Let me know if there is anything further I can do to test.

Is there a simple way of changing the ATA driver msg_enable bits without re-compiling?

Regards,
Giuliano Procida.

--- Comment #3 from Alan <[email protected]> 2012-07-01 23:39:02 --- Unless you can find an old release that did work (if one ever did) it'll be very hard to do much about. No docs.
