[Bug 285892] Re: ata1.00: exception Emask 0x0 SAct 0x807f SErr 0x0 action 0x6 frozen

Hi there, libata.noacpi=1 seems to have no side-effects... the only
kernel switch that had a side effect was libata.force=norst which
prevents soft and hard link resettings. If you have that switch on, when
this bug comes up, there is a system lock down (because obviously the
kernel prevented the soft & hard resetting.) Other switches had no
effect, and I gave up trying.

I am furious about AMD SB700... but M3A78-EM is a good board. I think
your notebook uses Intel chipset, and it's funny that it's also
occurring with Seagate.

I may replace the SAMSUNG drive first, we see how it goes (I need a
larger one anyway).
