Hello, I got a similar problem on my HP Pavilion dv6391 laptop (runs on a Turion X2 processor): Feisty (AMD64) Live CD does freezes When booting Feisty (AMD64) after being installed on my harddisk, it freezes at the "Loading hardware drivers..." stage, unless I run it with acpi=off
Gutsy Live CD works (I used the 23/7 CD image), yet also the installed version doesn't boot unless I use acpi=off option. Note that with this option, some things don't work, like the system beep and the USB (inserting a flash disk causes nothing to happen, not even detected in dmesg output). I think this dmesg error is related to USB: [ 438.030260] irq 7: nobody cared (try booting with the "irqpoll" option) [ 438.030336] [ 438.030336] Call Trace: [ 438.030339] <IRQ> [<ffffffff8026aabe>] __report_bad_irq+0x1e/0x80 [ 438.030361] [<ffffffff8026ada3>] note_interrupt+0x283/0x2c0 [ 438.030369] [<ffffffff8026ba20>] handle_edge_irq+0xe0/0x150 [ 438.030376] [<ffffffff8020c6bb>] do_IRQ+0x7b/0x100 [ 438.030380] [<ffffffff80209010>] default_idle+0x0/0x40 [ 438.030384] [<ffffffff8020a3a1>] ret_from_intr+0x0/0xa [ 438.030386] <EOI> [<ffffffff804216e0>] unix_poll+0x0/0xb0 [ 438.030397] [<ffffffff80209039>] default_idle+0x29/0x40 [ 438.030401] [<ffffffff802090c0>] cpu_idle+0x70/0xc0 [ 438.030414] [ 438.030415] handlers: [ 438.030477] [<ffffffff88023d10>] (usb_hcd_irq+0x0/0x60 [usbcore]) [ 438.030654] Disabling IRQ #7 also I keep getting this: [ 596.319878] Trying to free already-free IRQ 0 [ 596.588211] bcm43xx: Cannot register IRQ0 The complete dmesg output is attached ** Attachment added: "dmesg output" http://launchpadlibrarian.net/8578229/dmesg.log -- Ubuntu installation (and live-CD) unable to boot in HP Pavilion tx1020 laptop (AMD64, tablet), hangs https://bugs.launchpad.net/bugs/103273 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
