           Summary: System freezes after I/O on pata_jmicron device
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.24.3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IDE
        AssignedTo: io_ide@kernel-bugs.osdl.org
        ReportedBy: jniklast@web.de


Latest working kernel version: 2.6.23.17
Earliest failing kernel version: 2.6.24.0
Distribution: Gentoo
Hardware Environment: JMicron 20360/20363 AHCI Controller (rev 02) on Asus P5W
DH Deluxe Mainboard (Intel 975X + ICH7R chipset)
Software Environment: gcc 4.1.2, binutils 2.18, glibc 2.6.1-r0
Problem Description:
I have pata_jmicron as a module and use a IDE-Harddisk on the JMicron
controller. Whenever I do some I/O on that harddisk the I/O waiting load goes
up within a few seconds until it is at or close to 100% which renders the
system unusable. Magic SysRq makes a graceful reboot possible sometimes.
Steps to reproduce:
1. Do some I/O on a IDE-Harddisk which uses pata_jmicron
