Kernel crash with page_unlock: page ffffffff85768160 is not locked

Hello,

I'm desesperately looking for help to resolve this random kernel crash on solaris 10 x86. I tried to do some kernel debugging without success. I changed the server, the memory, the cpu, installed the latest patch cluster. I also bought a support contract on sun.com but they lost my purchase and after 2 weeks, i still don't have the support i paid for.

Thank you !

panic[cpu3]/thread=fffffe8000653c80:

    Bump!

    EricC, I don't suppose you ever found the solution to this? I'm having the same problem, exact same panic error, happens every couple weeks or so.

    Were you using the iSCSI initiator? I'm wondering if that has anything to do with it.

    Anyone have any tips for finding more information on the cause of this panic?
