My R50 also does it, has an ATI radeon 9000, IBM model number 1836-3UU. I also happen to have crytoroot and crypted swap, have only tried suspend to ram, not hibernate as I assume crypted swap wouldn't work anyway.
My panic looks like the one posted, similar stack trace and all. -- IBM T41 under Edgy: Kernel Panic for Suspend/Hibernate https://launchpad.net/bugs/62196 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
