I'm having the same problem with my Acer Travelmate 8215WLMI. Now, funny as it seems, since Ubuntu 11 I have to use "blacklist.firewirewire_ohci=yes" as a work-around, "blacklist=firewire_ohci" just wouldn't work. I'm actually using Ubuntu 12.04.5 Kernel 3.2.0-67. Trying Ubuntu 14 using the work-around and alternatively trying "blacklist=firewire_ohci" fails at booting with "firewire_ohci .....:failed to set link power". I tried booting with USB-stick and as well DVD.
Seems the newer Kernel not only keeps on with the same bug, but to worsen the situation ignores the blacklist command. Anything else that I could do? ** Attachment added: "P5.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981936/+attachment/4173331/+files/P5.jpg -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/981936 Title: 1217:00f7 [TravelMate 8200] Firewire prevents booting Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Incomplete Bug description: When trying to boot using kernel 3.2.x kernel the screen just goes blank and harddisk IO stops.
