Good catch... I uncommented the good lines under my debian in syslog.conf and I think I can give some more informations... First all tests I've just done are under kernel 2.6.8-rc2 on USB 2.0 port and with doing a "rmmod ehci_hcd".... and the thing that you have to notice is that sometime, not very often, things work just okay... OK now let's see three different trace I have had when my computer just hang (I repeat I never had this problem with kernel 2.4) OK now first with udev activated (Hand written what I have on my screen before hang) : --- R0 Stat 0x0 Attached scsi removable disk sda at scsi1, channel 0, id0, lun 0 usb-storage : scsci cmd done, result=0x0 usb-storage : queuecommand called Attached scsi removable disk sda at scsi1, channel 0, id0, lun 0 usb-storage: *** thread sleeping usb-storage: *** thread awakened usb-storage: Bad target number (6:0) usb-storage: scsi cmd done, result =0x 40000 usb-storage: queuecommand called usb-storage: *** thread sleeping usb-storage: *** thread awakened usb-storage: Bad target number (7:0) usbcore: registered new driver USB Mass Storage support registered usb.agent [4855] : usb-storage: loaded successfully usb-storage: scsi cmd done result=0x 40000 USB Mass Storage device found at 2 usbcore: registered new driver usb-storage USB Mass Storage support registered usb-storage: *** thread sleeping udev[4968]: creating device node '/dev/sda' udev[4968]: creating device node '/dev/sda1' OK now second one with udev deactivated (Hand written what I have on my screen before hang) : --- usb-storage:*** thread awakened usb-storage:Command ALLOW_MEDIUM_REMOVAL (6 bytes) usb-storage: 1e 00 00 00 00 00 usb-storage: Bulk Command S 0x43425355 T 0x11e L 0 F0 Trg 0 LUN 0 CL 6 usb-storage: usb_stor_bulk_transfer_buf : xfer 31 bytes usb-storage: Status code 0, transferred 31/31 usb-storage: --transfer complete usb-storage: Bulk command transfer result=0 usb-storage: Attempting to get CSW... usb-storage: usb_stor_bulk_transer_buf: xfer 13 bytes usb-storage: Status code 0; transferred 13/13 usb-storage: --transfer complete usb-storage: Bulk status result=0 usb-storage: Bulk Status S 0x53425355 T 0x11e R 0 Stat 0x0 Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0 usb-storage: scsi cmd done, result=0x0 Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0 usb-storage: *** thread sleeping If I have some extra time I will try with different kernel if it make a difference.... And I will try without removing ehci_hcd I think that there are more than one problem perhaps...thread ? sleep too short ?
