Hello ! Thank you steph33560. Here is my experience, just to help finding this post while looking for " ata2.00 etc." in crawlers. My Ubuntu 8.04 (hardy heron) kernel 2.6.24-19-generic didn't startup properly about 4 times per 5. Hardware : Dell Vostro 200 (SATA disk). It worked fine with 2.6.22-14-generic kernel version. And usually, it started up properly after one boot with that older kernel first. Here is the busybox I got when it failed : [code] [...]ata1.00: revalidation failed (errno = -5) [...]ata2.00: exception Emask 0x0 SAct 0x0 Serr 0x0 action 0x2 frozen [...]ata2.00: cmd a0/00:00:00:24:00/00:00:00:00/a0 tag 0 pio 36 in [...]ata2.00: satus { DRDY } [...]ata2.00: WARNING synchronous SCSI scan failed [/code] What steph33560 wrote solve it, THANKS A LOT ! Help for beginners : To apply the change in /boot/grub/menu.lst Launch a Terminal (Application/accessories/Terminal) Type the following commands : $ cd /boot/grub $ sudo cp menu.lst menu.lst.backup (Type your own password when asked and go on.) $ sudo vi menu.lst -> You enter in vi editor to apply changes in the file menu.lst -> Move forward until the first line begining with "kernel" (without any #) -> Type i to begin inserting text -> Delete "quiet splash" at the end of the line and replace it by "irqpoll all_generic_ide" as steph33560 said -> Press Echap to finish insert mode -> Type :wq and Enter to save and exit. $ exit You may now reboot your computer, it should work. -- ATA Revalidation Failed https://bugs.launchpad.net/bugs/206635 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
