From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113 Description of problem: I believe I've found a Bug on USB support on Core 2, Test 3. When I mount a CF reader as filesystem and try to copy the files across, it gets stuck and generates a bunch of messages to /var/log/messages. I've tested the same scenario on Core 1 and the problem doesn't reproduces, so I assume is a Core 2 problem. Here are the steps to reproduce the problem: 1) add the following line to /etc/fstab: usbdevfs /proc/bus/usb usbdevfs defaults 0 0 2) mkdir /mnt/usb 3) mount -t vfat /dev/sda1 /mnt/usb 4) mkdir /tmp/test 5) cp /mnt/usb/dcim/115canon/* /tmp/test cp: reading `/mnt/usb/dcim/115canon/img_1517.jpg': Input/output error Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. mkdir /mnt/usb 2. mount -t vfat /dev/sda1 /mnt/usb 3. mkdir /tmp/test 4. cp /mnt/usb/dcim/115canon/* /tmp/test Please see description for FULL details Actual Results: cp: reading `/mnt/usb/dcim/115canon/img_1517.jpg': Input/output error Expected Results: no error msg (success) Additional info: I also get the following errors on /var/log/messages: May 16 22:37:55 neo kernel: usb 1-2: new full speed USB device using address 7 May 16 22:37:55 neo kernel: scsi6 : SCSI emulation for USB Mass Storage devices May 16 22:37:55 neo kernel: Vendor: LEXAR Model: CF CARD Rev: 1.00 May 16 22:37:55 neo kernel: Type: Direct-Access ANSI SCSI revision: 02 May 16 22:37:55 neo kernel: SCSI device sdc: 1001952 512-byte hdwr sectors (513 MB) May 16 22:37:55 neo kernel: sdc: assuming Write Enabled May 16 22:37:55 neo kernel: sdc: assuming drive cache: write through May 16 22:37:55 neo kernel: sdc: sdc1 May 16 22:37:55 neo kernel: Attached scsi removable disk sdc at scsi6, channel 0, id 0, lun 0 May 16 22:37:56 neo scsi.agent[4649]: disk at /devices/pci0000:00/0000:00:1d.0/usb1/1-2/1-2:1.0/host6/6:0:0:0 May 16 22:37:57 neo udev[4786]: creating device node '/udev/sdc1' May 16 22:37:57 neo udev[4785]: creating device node '/udev/sdc' May 16 22:44:02 neo kernel: SCSI error : <6 0 0 0> return code = 0x6000000 May 16 22:44:02 neo kernel: end_request: I/O error, dev sdc, sector 149593 May 16 22:44:02 neo kernel: Buffer I/O error on device sdc1, logical block 149530 May 16 22:47:02 neo kernel: SCSI error : <6 0 0 0> return code = 0x6000000 May 16 22:47:02 neo kernel: end_request: I/O error, dev sdc, sector 149721 May 16 22:47:02 neo kernel: Buffer I/O error on device sdc1, logical block 149658
Key 6 means that media was removed. Beyond that it's hard to tell what's happening.
still a problem with the latest errata kernel ?
No, it works OK now.
