Bad version: 2.6.31-rc8 Last known good: 2.6.31-rc7 Observed on two different machines. Upgraded Debian Testing. udev 0.141-2 hal 0.5.12~git20090406.46dc48-2 usbutils 0.84-1 ============================== Descriptions: 1. When plug usb flash drive and turn on computer, device manager in KDE4 show it, and I can mount. When remove device very often icon doesn't dissapear - KDE doesn't refresh informaton about connected devices. When connect again, I can't mount it. 2. Sometimes when I remove and connect device again, then is listed twice: http://unixy.pl/maciek/download/kernel/2.6.31-rc8/zlom/snap1.jpg http://unixy.pl/maciek/download/kernel/2.6.31-rc8/zlom/snap2.jpg 3. Plug in flash drive (a), then flash drive (b), remove (a or b), remove (b or a), KDE still shows icons of flash drive (a/b) 4. Similar with USB printer 5. I this cases (1-4) lsusb doesn't show connected devices 6. VirtualBox also has similar problem connect with USB devices. ============================== For example: a) Connect flash drive, turn on computer (similar when plug device after boot): maciek@zlom:~/Desktop$ lsusb [...] Bus 001 Device 002: ID 3538:0054 Power Quotient International Co., Ltd Flash Drive (2GB) [...] b) Mount: lshal: 15:12:56.866: volume_uuid_599D_1168 property volume.mount_point = '/media/pqi' 15:12:56.867: volume_uuid_599D_1168 property volume.is_mounted = true c) Unmount: lshal: 15:13:46.528: volume_uuid_599D_1168 property volume.mount_point = '' 15:13:46.529: volume_uuid_599D_1168 property volume.is_mounted = false maciek@zlom:~/Desktop$ lsusb [...] Bus 001 Device 002: ID 3538:0054 Power Quotient International Co., Ltd Flash Drive (2GB) [...] d) Remove device: lshal: <doesn't show anything> KDE4 device manager still shows icon of flash drive maciek@zlom:~/Desktop$ lsusb Bus 005 Device 003: ID 062a:0201 Creative Labs Defender Office Keyboard (K7310) S Zodiak KM-9010 Bus 005 Device 002: ID 1020:0206 Labtec Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub dmesg: [ 385.848532] usb 1-1: USB disconnect, address 2 e) Connect device: lshal: <doesn't show anything> maciek@zlom:~/Desktop$ lsusb Bus 005 Device 003: ID 062a:0201 Creative Labs Defender Office Keyboard (K7310) S Zodiak KM-9010 Bus 005 Device 002: ID 1020:0206 Labtec Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub (can't see flash drive) dmesg: [ 483.727044] usb 1-1: new high speed USB device using ehci_hcd and address 5 [ 483.843749] usb 1-1: configuration #1 chosen from 1 choice [ 483.844012] scsi5 : SCSI emulation for USB Mass Storage devices [ 483.844222] usb-storage: device found at 5 [ 483.844225] usb-storage: waiting for device to settle before scanning [ 488.845138] scsi 5:0:0:0: Direct-Access pqi IntelligentStick 0.00 PQ: 0 ANSI: 2 [ 488.845354] sd 5:0:0:0: Attached scsi generic sg2 type 0 [ 488.846588] usb-storage: device scan complete [ 488.846621] sd 5:0:0:0: [sdb] 2015231 512-byte logical blocks: (1.03 GB/983 MiB) [ 488.847350] sd 5:0:0:0: [sdb] Write Protect is off [ 488.847355] sd 5:0:0:0: [sdb] Mode Sense: 00 00 00 00 [ 488.847359] sd 5:0:0:0: [sdb] Assuming drive cache: write through [ 488.850727] sd 5:0:0:0: [sdb] Assuming drive cache: write through [ 488.850733] sdb: sdb1 [ 488.960371] sd 5:0:0:0: [sdb] Assuming drive cache: write through [ 488.960377] sd 5:0:0:0: [sdb] Attached SCSI removable disk ============================== I try bisect, but I'm not sure that results is good: root@zlom:/usr/src/git/linux-2.6# git bisect good 1e23502cc57cef33455ac7cb9111e3c6d991a894 is first bad commit root@zlom:/usr/src/git/linux-2.6# git show 1e23502cc57cef33455ac7cb9111e3c6d991a894 commit 1e23502cc57cef33455ac7cb9111e3c6d991a894 Merge: e99b1f2 3161e45 Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx> Date: Wed Aug 26 20:54:48 2009 -0700 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6 * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: virtio: net refill on out-of-memory smc91x: fix compilation on SMP Config: http://unixy.pl/maciek/download/kernel/2.6.31-rc8/zlom/config-2.6.31-rc8 dmesg: http://unixy.pl/maciek/download/kernel/2.6.31-rc8/zlom/dmesg-2.6.31-rc8.txt I have no idea, how debug it.
