Comment 18 for bug 206635

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.
