Date: Wed, 20 Sep 2006 15:19:15 +0200 From: Petter Sundlöf <petter.sundlof@...dus.dhs.org> To: linux-kernel@...r.kernel.org Subject: Buffer I/O error on Sony Ericsson W810i (writing/sync to memory stick duo via phone's USB) Running 2.6.17 (Debian unstable 2.6.17-2-k7). When after a copy operation I unmount the phone's smart card, the unmount stalls, and gives these errors in syslog Buffer I/O error on device sdg1, logical block 960472 Buffer I/O error on device sdg1, logical block 960473 Buffer I/O error on device sdg1, logical block 960474 Buffer I/O error on device sdg1, logical block 960475 Buffer I/O error on device sdg1, logical block 960476 Buffer I/O error on device sdg1, logical block 960477 Buffer I/O error on device sdg1, logical block 960478 Buffer I/O error on device sdg1, logical block 960479 Buffer I/O error on device sdg1, logical block 960472 Buffer I/O error on device sdg1, logical block 960473 Sep 20 15:13:27 localhost NetworkManager: <debug info>^I[1158758007.553073] nm_hal_device_added (): New device added (hal udi is '/org/freedesktop/Hal/devices/storage_serial_Sony_Ericsson_Sony_Ericsso n_W810_359063000528328_0_0'). Sep 20 15:13:28 localhost NetworkManager: <debug info>^I[1158758008.701140] nm_hal_device_added (): New device added (hal udi is '/org/freedesktop/Hal/devices/volume_uuid_4511_4C30'). The card is a 512MB SanDisk Memory Stick PRO Dudo (labelled MagicGate). After the start of the umount, 'df' starts reporting the device as much larger than it is: /dev/sdg1 4,6G 4,3G 143M 97% /media/PHONE CARD Before the unmount it reports it correctly. The unmount operation never stops, and the files are not successfully copied. I also tried to manually run 'sync' manually, and after a long, long while -- like 4-5 minutes, it exited, and I could unmount it gracefully. The copy operation seems to have worked fine in this case. Anyone using the same device with greater success? How can I easily debug this?
