Hi, I am trying to track down an issue that happen during Debian Installation from a USB key onto a Mac Mini G4 (PPC) [*]. Basically the USB key is working nicely (`badblocks` is fine), however under this specific circumstances, the USB key needs to be physically removed and then re-plugged so that it can be read. dmesg log excerpt: [ 4.259597] scsi 2:0:0:0: Direct-Access SanDisk Cruzer Mini 0.2 PQ: 0 ANSI: 2 [ 4.265282] sd 2:0:0:0: [sdb] 2001888 512-byte logical blocks: (1.02 GB/977 MiB) [ 4.267027] sd 2:0:0:0: [sdb] Write Protect is off [ 4.267040] sd 2:0:0:0: [sdb] Mode Sense: 03 00 00 00 [ 4.268149] sd 2:0:0:0: [sdb] No Caching mode page found [ 4.268162] sd 2:0:0:0: [sdb] Assuming drive cache: write through [ 4.393824] usb 1-2: reset high-speed USB device number 3 using ehci-pci [ 4.653835] usb 1-2: reset high-speed USB device number 3 using ehci-pci [ 4.913832] usb 1-2: reset high-speed USB device number 3 using ehci-pci [ 5.177821] usb 1-2: reset high-speed USB device number 3 using ehci-pci [ 5.437844] usb 1-2: reset high-speed USB device number 3 using ehci-pci [ 5.697847] usb 1-2: reset high-speed USB device number 3 using ehci-pci [ 5.831893] sd 2:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [ 5.831913] sd 2:0:0:0: [sdb] tag#0 CDB: Read(10) 28 00 00 00 00 00 00 00 08 00 [ 5.831919] blk_update_request: I/O error, dev sdb, sector 0 [ 5.831926] Buffer I/O error on dev sdb, logical block 0, async page read I failed so far to reproduce it, since anytime I try to `mount` it it works. Comments welcome on how to track this down ?
