Adding "nosmp" to kernel parameters seems to have done it for me. Works just fine and I am using ndiswrapper right now. I would really like to know now, to ensure that this is smp related (and not only in my case) that if you have smp systems as well, and if nosmp helps you also. thx Jinn -- BCM1390M (broadcom 4311) with ndiswrapper and nvidia IRQ conflicts https://launchpad.net/bugs/57355 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
