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

[Krzysztof Krzyzanowski]

Same bug here - I encountered it both on lucid kernel (2.6.32-22) and 2.6.34rc6 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc6-lucid/
I'm struggling with that problem on desktop computer with Samsung HDD
