Also the delay between the kernel uevent and the udev udev event can be investigated: pim:/home/kay/src/udev-kay # ./udevmonitor UEVENT[1122920113] add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1 UEVENT[1122920113] add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1:1.0 UEVENT[1122920113] add@/class/scsi_host/host12 UEVENT[1122920113] add@/class/usb_device/usbdev2.99 UEVENT[1122920113] add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1:1.0/host12/target12:0:0/12:0:0:0 UDEV [1122920113] add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1 UEVENT[1122920113] add@/block/sda UEVENT[1122920113] add@/class/scsi_generic/sg0 UEVENT[1122920113] add@/class/scsi_device/12:0:0:0 UDEV [1122920113] add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1:1.0 UDEV [1122920113] add@/class/scsi_host/host12 UDEV [1122920113] add@/class/usb_device/usbdev2.99 UDEV [1122920113] add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1:1.0/host12/target12:0:0/12:0:0:0 UDEV [1122920113] add@/block/sda UDEV [1122920113] add@/class/scsi_generic/sg0 UDEV [1122920113] add@/class/scsi_device/12:0:0:0 UEVENT[1122920115] add@/block/sda/sda1 UDEV [1122920115] add@/block/sda/sda1 pim:/home/kay/src/udev-kay # ./udevmonitor --env UDEV [1122920185] add@/block/sda/sda1 ACTION=add DEVPATH=/block/sda/sda1 SUBSYSTEM=block SEQNUM=2159 MINOR=1 MAJOR=8 PHYSDEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1:1.0/host13/target13:0:0/13:0:0:0 PHYSDEVBUS=scsi PHYSDEVDRIVER=sd UDEVD_EVENT=1 UDEV_LOG=3 ID_VENDOR=IBM ID_MODEL=Memory_Key ID_REVISION=3.04 ID_SERIAL=IBM_Memory_Key_0218B301030027E8 ID_TYPE=disk ID_BUS=usb ID_PATH=usb-0218B301030027E8:0:0:0 ID_FS_USAGE=filesystem ID_FS_TYPE=vfat ID_FS_VERSION=FAT16 ID_FS_UUID=42D8-9E02 ID_FS_LABEL_SAFE=s_p_c DEVNAME=/dev/sda1 Signed-off-by: Kay Sievers <kay.sievers@suse.de>
