You must provide the exact version of the kernel you are running. Fedora kernels that I am running: 2.6.12-cor (custom compile) 2.6.12-1.1398_FC4 2.6.11-1.1369_FC4 I experience the problem with all three kernels. can you attach the output of dmesg after inserting the device please ? #after attaching the device for the first time in several hours usb 5-1: new full speed USB device using uhci_hcd and address 4 Initializing USB Mass Storage driver... scsi5 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 2 usb-storage: waiting for device to settle before scanning Vendor: USB2.0 Model: CardReader CF RW Rev: 0.0> Type: Direct-Access ANSI SCSI revision: 00 Attached scsi removable disk sdb at scsi5, channel 0, id 0, lun 0 Vendor: USB2.0 Model: CardReader Combo Rev: 0.0> Type: Direct-Access ANSI SCSI revision: 00 Attached scsi removable disk sdc at scsi5, channel 0, id 0, lun 1 usb-storage: device scan complete # and only AFTER I disconnected the device did the below appear ... scsi6 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 4 usb-storage: waiting for device to settle before scanning usbcore: registered new driver usb-storage USB Mass Storage support registered. usb 5-1: USB disconnect, address 4 #plugging it back in usb 5-1: new full speed USB device using uhci_hcd and address 5 #nothing more for a minute or two... #then after disconnecting it again... scsi7 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 5 usb-storage: waiting for device to settle before scanning usb 5-1: USB disconnect, address 5 Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks. I installed kernel i686 2.6.13-1.1526_FC4 and booted to it without issue. Unfortunately, the problem remains. I detected no change in behavior. I'd like to see an output of alt-sysrq-t. Please kill all unrelated processes and do it while in text mode at init level 3 (to get rid of X) The objective here is to capture the cat which hangs, khubd, and usb-storage threads. Please do not drop the dmesg into the comments box, attach instead. 2.6.14-1.1637_FC4 has been released as an update for FC4. Please retest with this update, as a large amount of code has been changed in this release, which may have fixed your problem. Thank you. This is a mass-update to all currently open kernel bugs. A new kernel update has been released (Version: 2.6.15-1.1830_FC4) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed.

If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. Thank you. Closing per previous comment. |
