Package: linux-image-2.6.23-1-amd64 Version: 2.6.23-2 Severity: important *** Please type your report below this line ***
I seem to have run into some sort of io kernel bug. I connected a usb drive (trekstor datastation pocket x.u), mounted a partition, juggled data around (tens of GB), and umounted it. When i removed the drive from the usb port, I ran into a kernel bug. I have used this disk and enclosure combo with this machine and kernel before without any problem, also shuffling lots of data, though maybe not quite as much. An e2fsck on the mounted partition turned up no errors. Astrid Here is the relevant part of the dmesg output: usb 5-2: new high speed USB device using ehci_hcd and address 14 usb 5-2: configuration #1 chosen from 1 choice Initializing USB Mass Storage driver... scsi4 : SCSI emulation for USB Mass Storage devices usbcore: registered new interface driver usb-storage USB Mass Storage support registered. usb-storage: device found at 14 usb-storage: waiting for device to settle before scanning usb-storage: device scan complete scsi 4:0:0:0: Direct-Access WDC WD16 00BEVE-00UYT0 0000 PQ: 0 ANSI: 0 sd 4:0:0:0: [sdb] 312581808 512-byte hardware sectors (160042 MB) sd 4:0:0:0: [sdb] Write Protect is off sd 4:0:0:0: [sdb] Mode Sense: 27 00 00 00 sd 4:0:0:0: [sdb] Assuming drive cache: write through sd 4:0:0:0: [sdb] 312581808 512-byte hardware sectors (160042 MB) sd 4:0:0:0: [sdb] Write Protect is off sd 4:0:0:0: [sdb] Mode Sense: 27 00 00 00 sd 4:0:0:0: [sdb] Assuming drive cache: write through sdb: sdb1 sd 4:0:0:0: [sdb] Attached SCSI disk kjournald starting.
