https://bugzilla.kernel.org/show_bug.cgi?id=42783 Summary: Kernel ooops when disconnecting the USB flash disk, in which I've just modified partition table Product: IO/Storage Version: 2.5 Kernel Version: 3.2.2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: SCSI AssignedTo: linux-scsi@xxxxxxxxxxxxxxx ReportedBy: wzab@xxxxxxxxxxxxx Regression: No I have added the "boot" flag to the /dev/sdb1 partition in the flash disk. After that I ran the "sync" command, and after a few seconds I have unplugged the USB stick from the PC. It resulted in the ooops report shown below: Feb 16 15:33:31 WZLap kernel: [ 4477.732803] scsi 7:0:0:0: Direct-Access Kingston DataTraveler 2.0 PMAP PQ: 0 ANSI: 0 CCS Feb 16 15:33:32 WZLap kernel: [ 4477.976629] sd 7:0:0:0: [sdb] 1953792 512-byte logical blocks: (1.00 GB/954 MiB) Feb 16 15:33:32 WZLap kernel: [ 4477.977198] sd 7:0:0:0: [sdb] Write Protect is off Feb 16 15:33:32 WZLap kernel: [ 4477.981242] sdb: sdb1 Feb 16 15:33:32 WZLap kernel: [ 4477.983462] sd 7:0:0:0: [sdb] Attached SCSI removable disk Feb 16 15:37:23 WZLap kernel: [ 4709.469769] sdb: sdb1 Feb 16 15:38:00 WZLap kernel: [ 4745.877869] FAT-fs (sdb1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
