Description of problem: This trouble a get on Fedora 14 i686/x86_64 (GNOME) and Fedora 15 x86_64 (GNOME). If connect USB HDD (I'm using Samsung HX-M101TAB/G 1TB "2.5" USB 3.0) to my computer the system find it success, copy data to HDD or read data from HDD success. But if I safely remove HDD from my computer the system is freezing (Fedora 14) or kernel panic (Fedora 15). Also I get this bug with 3Q USB HDD. On Seagate USB this NO reproduce. Steps to Reproduce: 1. Connect USB HDD Samsung or 3Q to computer. 2. Copy or read data from HDD. 3. In GNOME right click mouse on HDD and select Safely remove from menu. 4. Your get freez or kernel panic. Additional info: This bug reproduce not only for me, see https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/844957
what kernel version ? this should be fixed in the 2.6.40 updates.
(In reply to comment #1) > what kernel version ? > > this should be fixed in the 2.6.40 updates. On Fedora 15 I'm having x86_64 2.6.40.4 (last update 18.09.2011) On Fedora 14 I'm having i686/x86_64 2.6.35.14. The 3Q USB HDD hangs Fedora 14 (Fedora 15 not tested), Samsung USB HDD HX-M101TAB causes kernel panic on Fedora 15 x86_64 and Fedora 14 (i686/x86_64) (all system with GNOME). If I umount HDD use following command (from root): "umount /dev/sdb" that umount success (no hangs and no kernel panic). P.S. I am sorry for my ugly english.
hmm. we really need to know more about that panic. if you could capture the trace somehow (even if it's a photo) that would be great.
also, what filesystem is on the external drive ?

(In reply to comment #4) > also, what filesystem is on the external drive ? I use NTFS file system (for more compability). Today I'm exchanging Samsung HDD on Seagte USB 3.0 HDD (FreeAgent GoFlex 1TB). But on Segate with USB 3.0 this bug reproduce. I think the problem lies in the USB 3.0 controller HDD.
There is still fallout from that mess, and newly proposed patches to fix it: https://lkml.org/lkml/2011/9/20/31 https://lkml.org/lkml/2011/9/18/124
