I just report that the fresh change in vt6421_set_dma_mode does not solve (for me) the stable problem described at http://lkml.org/lkml/2009/10/11/36 "Lots of 6421 setups do not work". Relaxed reading still works, intensive reading still fails. NB: the patch had been applied to 2.6.32-rc5 instead of Linux-next. ======= root@test:~# modinfo sata_via filename: /lib/modules/2.6.32-rc5/kernel/drivers/ata/sata_via.ko author: Jeff Garzik description: SCSI low-level driver for VIA SATA controllers license: GPL version: 2.5 vermagic: 2.6.32-rc5 mod_unload PENTIUMII ====== root@test:~# lspci 00:00.0 Host bridge: Intel Corporation 82815 815 Chipset Host Bridge and Memory Controller Hub (rev 04) 00:01.0 PCI bridge: Intel Corporation 82815 815 Chipset AGP Bridge (rev 04) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 02) 00:1f.0 ISA bridge: Intel Corporation 82801BA ISA Bridge (LPC) (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801BA IDE U100 Controller (rev 02) 00:1f.2 USB Controller: Intel Corporation 82801BA/BAM USB Controller #1 (rev 02) 00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus Controller (rev 02) 00:1f.4 USB Controller: Intel Corporation 82801BA/BAM USB Controller #1 (rev 02) 01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400] (rev b2) 02:03.0 RAID bus controller: VIA Technologies, Inc.
