I believe i am experiencing the same problem: feisty livecd (32-bit - I haven't tried 64) won't boot, "acpi=off" and/or "irqpoll" seem to have no effect.
I'm running an E6600 on an ASUS P5B (Intel P965 Express, Intel ICH8, JMicron JMB363, Realtek Gigabit LAN, SoundMAX Audio) with an NVidia 7300GT I am currently using 32bit Dapper, so if there's any hardware output needed, I can get it from there. uname -a: Linux coreduroy32 2.6.15-28-686 #1 SMP PREEMPT Thu Feb 1 16:14:07 UTC 2007 i686 GNU/Linux I've attached the output from lspci-vvnn and dmesg if that helps. Note that I currently have a multihead S3 savage in here, rather than the 7300GT at the moment. I have yet to try booting Feisty with only this video card, but will give it a go later today. ** Attachment added: "output from dmesg on dapper32" http://librarian.launchpad.net/6825708/dmesg.log -- 7.04 herd 5 liveCD will not boot https://launchpad.net/bugs/89380 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
