Subjectexception Emask 0x0 SAct 0x1 / SErr 0x0 action 0x2 frozen
I could not agree more.

CC'ing the relevant mailing lists to see if someone out there has any idea
what more we could do as this has been affecting you (more so than myself,
but I would still like to get some sort of resolution as well, as it still
happens to me too):

Similar, but not the same issue:

Sep 17 20:20:05 p34 kernel: [1422169.440538] ata5.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
