This is a common EHCI problem on all S5PV210 Linux boards. We can reproduce this also by using mass storage device and copy large files. Here we see lot of NAK with IN transaction on USB when write the copied data to stick. And we see lot of invalid transactions. Here you see output when plug a usb mass storage device (with 4 port usb hub) and then mounting the device and copy a large file. After reading the file we get the NAKs and linux reinit the usb. usb 1-1: new high-speed USB device number 2 using s5p-ehci usb 1-1: New USB device found, idVendor=0409, idProduct=005a usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 hub 1-1:1.0: USB hub found hub 1-1:1.0: 4 ports detected usb 1-1.1: new high-speed USB device number 3 using s5p-ehci usb 1-1.1: New USB device found, idVendor=090c, idProduct=1000 usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1.1: Product: USB DISK usb 1-1.1: Manufacturer: SMI Corporation usb 1-1.1: SerialNumber: AA04012900007471 scsi0 : usb-storage 1-1.1:1.0 scsi 0:0:0:0: Direct-Access FlashPen Fancy 1100 PQ: 0 ANSI: 0 CCS sd 0:0:0:0: [sda] 1957888 512-byte logical blocks: (1.00 GB/956 MiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] No Caching mode page present sd 0:0:0:0: [sda] Assuming drive cache: write through sd 0:0:0:0: [sda] No Caching mode page present sd 0:0:0:0: [sda] Assuming drive cache: write through sda: sda1 sd 0:0:0:0: [sda] No Caching mode page present sd 0:0:0:0: [sda] Assuming drive cache: write through sd 0:0:0:0: [sda] Attached SCSI removable disk # mount /dev/sda1 /mnt # cd /mnt # ls test.mp3 # cp test.mp3 test.yy # usb 1-1.1: USB disconnect, device number 3 sd 0:0:0:0: Device offlined - not ready after error recovery sd 0:0:0:0: [sda] Unhandled error code sd 0:0:0:0: [sda] Result: hostbyte=0x01 driverbyte=0x00 sd 0:0:0:0: [sda] CDB: cdb[0]=0x2a: 2a 00 00 00 00 34 00 00 02 00 end_request: I/O error, dev sda, sector 52 Buffer I/O error on device sda1, logical block 20 lost page write due to I/O error on sda1 Buffer I/O error on device sda1, logical block 21 lost page write due to I/O error on sda1 sd 0:0:0:0: [sda] Unhandled error code sd 0:0:0:0: [sda] Result: hostbyte=0x01 driverbyte=0x00 sd 0:0:0:0: [sda] CDB: cdb[0]=0x2a: 2a 00 00 00 01 23 00 00 02 00 end_request: I/O error, dev sda, sector 291 Buffer I/O error on device sda1, logical block 259 lost page write due to I/O error on sda1 Buffer I/O error on device sda1, logical block 260 lost page write due to I/O error on sda1 usb 1-1.1: new high-speed USB device number 4 using s5p-ehci usb 1-1.1: New USB device found, idVendor=090c, idProduct=1000 usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1.1: Product: USB DISK usb 1-1.1: Manufacturer: SMI Corporation usb 1-1.1: SerialNumber: AA04012900007471 scsi1 : usb-storage 1-1.1:1.0 scsi 1:0:0:0: Direct-Access FlashPen Fancy 1100 PQ: 0 ANSI: 0 CCS sd 1:0:0:0: [sdb] 1957888 512-byte logical blocks: (1.00 GB/956 MiB) sd 1:0:0:0: [sdb] Write Protect is off sd 1:0:0:0: [sdb] No Caching mode page present sd 1:0:0:0: [sdb] Assuming drive cache: write through sd 1:0:0:0: [sdb] No Caching mode page present sd 1:0:0:0: [sdb] Assuming drive cache: write through sdb: sdb1 sd 1:0:0:0: [sdb] No Caching mode page present sd 1:0:0:0: [sdb] Assuming drive cache: write through sd 1:0:0:0: [sdb] Attached SCSI removable disk |
