Comment 11 for bug 228302

Is anyone even caring about this fucking bug ?!? Two monthes that it has been filed, and still open, still flagged as "New" and even still of "Undecided" importance while the solution is so well-known !!! (I didn't have access to the computer up to now)

The problem is related to the libATA. It is likely to be related to Intel's combined mode, however I found the solutions listed on libATA website only after solving the problem another way.

I suggest people to feedback after testing solutions given here : http://linux-ata.org/faq.html#combined

If it doesn't work (as I said I didn't test myself, found it too late), then try with "my" (actually well disseminated on the web) solution : add those lines to /etc/modprobe.d/blacklist :
blacklist pata_atiixp
blacklist pata_acpi
blacklist sg
blacklist sr_mod
blacklist sd_mod
(NB : it was not necessary for me to blacklist sg and sd_mod, but I had problems only with my DVD recorder)

/dev/sdX will become /dev/hdX and UUIDs will change, so don't forget to change entries in /etc/fstab (and maybe /boot/grub/menu.lst) and swap's UUID in /etc/initramsf-tools/conf.d/resume (and to "update-initramfs -u -k all" after this latter operation). [Reminder: "blkid" for knowing UUIDs]

Thanks guys.
