USB Stopped working with 2.6.26 kernel?
I have a Kingston 2GB MicroSD that can be accessed via a usb port.
The usb has an ext2 filesystem on in with an MBR installed for booting. Prior to the 2.6.26 kernel (the 2.25 series), I have had no trouble mounting, booting, or otherwise accessing the MicroSD system. With the release of the 2.6.26 and now the 2.6.26.1 kernel, the kernel fails to properly recognize the MicroSD. Has anybody else seen this and know of a solution or can point out a particular kernel git patch that may have caused this? fdisk will not read the usb and gparted thinks it is a 512b disk and not a 2048MB disk. Below is my dmesg log: usb 1-1: new high speed USB device using ehci_hcd and address 4 usb 1-1: configuration #1 chosen from 1 choice scsi7 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 4 usb-storage: waiting for device to settle before scanning usb-storage: device scan complete scsi 7:0:0:0: Direct-Access Generic 6000 PQ: 0 ANSI: 0 CCS sd 7:0:0:0: [sdb] Sector size 0 reported, assuming 512. sd 7:0:0:0: [sdb] 1 512-byte hardware sectors (0 MB) sd 7:0:0:0: [sdb] Write Protect is off sd 7:0:0:0: [sdb] Mode Sense: 4b 00 00 08 sd 7:0:0:0: [sdb] Assuming drive cache: write through sd 7:0:0:0: [sdb] Sector size 0 reported, assuming 512. sd 7:0:0:0: [sdb] 1 512-byte hardware sectors (0 MB) sd 7:0:0:0: [sdb] Write Protect is off sd 7:0:0:0: [sdb] Mode Sense: 4b 00 00 08 sd 7:0:0:0: [sdb] Assuming drive cache: write through sdb: sdb1 sdb: p1 exceeds device capacity sd 7:0:0:0: [sdb] Attached SCSI removable disk sd 7:0:0:0: Attached scsi generic sg2 type 0 attempt to access beyond end of device sdb: rw=0, want=3932032, limit=1 Buffer I/O error on device sdb1, logical block 3931776 attempt to access beyond end of device sdb: rw=0, want=3932033, limit=1 Buffer I/O error on device sdb1, logical block 3931777 attempt to access beyond end of device sdb: rw=0, want=3932034, limit=1 Buffer I/O error on device sdb1, logical block 3931778 attempt to access beyond end of device sdb: rw=0, want=3932035, limit=1 Buffer I/O error on device sdb1, logical block 3931779 attempt to access beyond end of device sdb: rw=0, want=3932036, limit=1 Buffer I/O error on device sdb1, logical block 3931780 attempt to access beyond end of device sdb: rw=0, want=3932037, limit=1 Buffer I/O error on device sdb1, logical block 3931781 attempt to access beyond end of device sdb: rw=0, want=3932038, limit=1 Buffer I/O error on device sdb1, logical block 3931782 attempt to access beyond end of device sdb: rw=0, want=3932039, limit=1 Buffer I/O error on device sdb1, logical block 3931783 attempt to access beyond end of device sdb: rw=0, want=3932032, limit=1 Buffer I/O error on device sdb1, logical block 3931776 attempt to access beyond end of device sdb: rw=0, want=3932033, limit=1 Buffer I/O error on device sdb1, logical block 3931777 attempt to access beyond end of device sdb: rw=0, want=3932034, limit=1 attempt to access beyond end of device sdb: rw=0, want=3932035, limit=1 attempt to access beyond end of device sdb: rw=0, want=3932036, limit=1 attempt to access beyond end of device sdb: rw=0, want=3932037, limit=1 attempt to access beyond end of device sdb: rw=0, want=3932038, limit=1 attempt to access beyond end of device sdb: rw=0, want=3932039, limit=1 attempt to access beyond end of device sdb: rw=0, want=256, limit=1 attempt to access beyond end of device sdb: rw=0, want=257, limit=1 attempt to access beyond end of device sdb: rw=0, want=258, limit=1 attempt to access beyond end of device sdb: rw=0, want=259, limit=1 attempt to access beyond end of device sdb: rw=0, want=260, limit=1 attempt to access beyond end of device sdb: rw=0, want=261, limit=1 attempt to access beyond end of device EDIT: Possible Solutions Found: http://www.gossamer-threads.com/list.../kernel/953404 http://marc.info/?l=linux-usb&m=121734710306509&w=2 |
This sounds similar to my problem.
I have a card reader 4in1 (Alcor Micro Corp.) integrated into the PC and another card reader 4in1 integrated into the USB printer (HP Photosmart 7260); both card readers are USB 1.x. With kernel 2.6.24.x both card readers work perfectly; if I insert a memory card, HAL can mount and unmount it automatically. After an upgrade to the kernel 2.6.25.x or 2.6.26.x, only the PC card reader works; the printer card reader has stopped working. Inserting a memory card I get these messages: Code:

In my case, patches do not work; the only solution is to reboot with kernel 2.6.24.x! I never understood the Linux world; if a piece of code works perfectly, why rewrite it? |
