http://bugzilla.kernel.org/show_bug.cgi?id=11735 Summary: delkin_cb fails after resume Product: IO/Storage Version: 2.5 KernelVersion: 2.6.27-rc9 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: bumble.bee@xxxxxxxxx Distribution: gentoo Hardware Environment: x86 (Dell laptop, yenta cardbus), "02:00.0 Mass storage controller [0180]: Workbit Corporation Device [1145:f021] (rev 01)" Problem Description: The delkin_cb driver works with ~3 mb/s performance, top shows the CPU in 98% wait state with heavy I/O. If you suspend to ram or disk, the system comes up but any further I/O to a CF card in the adapter will not complete, top shows ~100% wait state but commands to read from the card do not complete. pata_ninja32 not tested because it performs much worse than delkin_cb (~1 mb/s). Steps to reproduce: 1. boot, mount a CF card through the adapter (or have root on the CF card, as I do) 2. echo mem > /sys/power/state 3. resume from sleep 4. do I/O from the card, say "ls /mnt/card" 5. <crickets chirp> ... top shows 100% wait state -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
