Subject: WARNING: at drivers/ata/libata-eh.c:3247 ata_eh_finish+0x7c/0x8b()

Hi all,

Just hotplugged a suspect SATA hard drive into my system.  I guess it is 
suspect as there were media errors being logged, but I'm guessing this isn't 
supposed to happen:

I doubt the nvidia module has anything to do with this, but if you want me to 
reproduce this on a clean kernel let me know.  I can't reproduce it now as 
that SATA port appears to be dead...

Please let me know if you need any further info.

Cheers,
Adam.
