           Summary: SMC2835 : Prism54 1.2 gives kernel oops
           Product: prim54
           Version: 1.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: Device Driver
        AssignedTo: prism54-devel at prism54.org
        ReportedBy: d_leemans at pandora.be


OS : Slackware 10.0, kernel 2.6.8-rc2, ACPI enabled
HW : Toshiba Satellite Pro 6000 laptop, SMC2835 V2 card
firmware : 1.0.4.3

In an attempt to solve my resume problem in bug 97, I compiled 2.6.8-rc2, wich
uses the Prism54 1.2 driver. 

The result is even far worse now, as I stumble on a not so nice kernel oops, as
shown in this dmesg :

...
