           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@kernel-bugs.osdl.org
        ReportedBy: bumble.bee@xs4all.nl


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
