Hi, On a system (Commell LE365) with VIA CX700M chipset I experience varying resume results: When built with IDE subsystem and VIA82CXXX driver the system suspends and resumes properly [2.6.28]. ----- CONFIG_HAVE_IDE=y CONFIG_IDE=y CONFIG_IDE_TIMINGS=y CONFIG_IDE_GD=y CONFIG_IDE_GD_ATA=y CONFIG_BLK_DEV_IDEACPI=y CONFIG_BLK_DEV_IDEDMA_SFF=y CONFIG_BLK_DEV_IDEPCI=y CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_BLK_DEV_VIA82CXXX=y CONFIG_BLK_DEV_IDEDMA=y # CONFIG_ATA is not set ----- When built with ATA subsystem and PATA_VIA driver the system suspends but hangs during resume (HDD LED remains active) [2.6.28] though it manages to resume when the CompactFlash card is disconnected [2.6.27]. ----- # CONFIG_IDE is not set CONFIG_ATA=y CONFIG_ATA_ACPI=y CONFIG_SATA_AHCI=y CONFIG_ATA_SFF=y CONFIG_SATA_VIA=y CONFIG_PATA_VIA=y ----- Is there some known bigger difference between behavior of both drivers? I might start comparing behavior of both drivers and try to adjust PATA_VIA to successfully resume the system, though any hint/suggestion is welcome! - SATA HDD with system partition [seen as IDE Primary master] - CompactFlash card [seen as IDE Secondary slave] lspci output: 00:00.0 Host bridge [0600]: VIA Technologies, Inc.

VIA High Definition Audio Controller [1106:3288] (rev 10) Secondary note, with ATA subsystem it is possible to discover hot-plugged second SATA drive with issuing echo '- - -' > host0/scsi_host/host0/scan though the same action causes the access to first SATA drive to fail after removing second drive. (unfortunately BIOS does only allows configuring the chipset in IDE mode - so not possible to use SATA_VIA or AHCI). I guess this is caused by some incorrect detection of speed settings. What is the way to ask driver to rescan with IDE driver?
