Title: hdparm and ata_id makes USB drive hang Status in Linux: Invalid Status in hdparm package in Ubuntu: Invalid Status in linux package in Ubuntu: Won't Fix Bug description: I have installed Karmic on a USB drive. Because of bug #419231 I need to add ums_cypress to the initrd for this. During boot I noticed several long waits with no activity. Bootchart indicated it was hdparm hanging. When I run hdparm manually it hangs for 15 seconds: $ time sudo hdparm /dev/sdb /dev/sdb: HDIO_DRIVE_CMD(identify) failed: Invalid exchange readonly = 0 (off) readahead = 256 (on) geometry = 30401/255/63, sectors = 488397168, start = 0 real 0m15.979s user 0m0.000s sys 0m0.008s It leaves this in dmesg: [ 207.928097] usb 1-6: reset high speed USB device using ehci_hcd and address 2 [ 215.928057] usb 1-6: reset high speed USB device using ehci_hcd and address 2 [ 240.928054] usb 1-6: reset high speed USB device using ehci_hcd and address 2 [ 248.928049] usb 1-6: reset high speed USB device using ehci_hcd and address 2 [ 279.928054] usb 1-6: reset high speed USB device using ehci_hcd and address 2 [ 287.928107] usb 1-6: reset high speed USB device using ehci_hcd and address 2 [ 411.472048] ACPI: EC: missing confirmations, switch off interrupt mode.
