           Summary: hard lock with drivers for hpt374 sata controller
                    (Highpoint Rocket 1540)
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.23-rc2 (linus git tree as of 2007-08-06)
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: drivers_other at kernel-bugs.osdl.org
        ReportedBy: rah at bash.sh


Neither the hpt366.c or pata_hpt37x.c driver works with the Highpoint Rocket
1540.  With these[0][1][2][3] patches from Sergei Shtylyov, both drivers result
in some kernel output, listed below, followed by a hard lock.
