https://bugzilla.kernel.org/show_bug.cgi?id=44111 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: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: giuliano.procida@xxxxxxxxx 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: 04:00.0 IDE interface [0101]: VIA Technologies, Inc.

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