I can confirm this is happening for me in 12.10 3.7.0 kernel. No kernel logs since I can't get out of the fake ata NULLs but I managed to write down a few errors I noticed: Warning at: /build/buildd/linux-3.7.0/drivers/ata/libata_core.c 2947 ata_timing_find_mode +0x66/0x80() ata_timing_find_mode: unable to find timing for xfer_mode 0x0. Unable to handle NULL pointer dereference at 0000000000000010
It could be unrelated to this and more about USB devices but I'm going to try the kernels from 3c4cfadef6a1665d9cd02a543782d03d3e6740c6 anyway. However the 12.10 kernel 3.7.0 will boot with acpi=off but then my USB devices are not functional such as my mouse. When acpi is on, it will stop while adding USB devices such as my headset Roccat Kave and Ace Edge T2 and give the libata Warnings from above before the stop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1080320 Title: broken ACPI and fake disk errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1080320/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
