The "bug" is still here in 14.04.

$ uname -a
Linux valhalla 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 
x86_64 x86_64 x86_64 GNU/Linux

$ grep AHCI /boot/config-3.13.0-44-generic 
CONFIG_SATA_AHCI=m
CONFIG_SATA_AHCI_PLATFORM=m
# CONFIG_AHCI_IMX is not set
CONFIG_SATA_ACARD_AHCI=m

Yes, a workaround is to set BIOS to use IDE not AHCI but isn't AHCI
better than IDE? Hot-plug, queuing, etc. Specillay if you have a e-SATA
port.

Is it safe to hot-plug in IDE mode?
Is performance better in AHCI mode?
Why it is so problematic to include the AHCI driver compiled into the kernel?

Fortunately, I only reboot this computer from time to time :)
