At this point I'd appreciate some input from the kernel team what this
message actually means, and what the likely cause could be. It does not
really seem specific to either hdparm nor libatasmart, all they do is
things like
https://bugs.launchpad.net/ubuntu/karmic/+source/libatasmart/+bug/445852/comments/202
(i. e. using the normal SCSI ioctls).
One possible workaround might be to not run hdparm on SSD devices. This
only might fix the symptom, but it might be an appropriate SRU for
lucid.

+

+ (he's willing to provide access to other people for debugging).
+
+ A lot of different commands were tried to reproduce this at runtime,
+ like
+
+ # for i in `seq 50`; do skdump --can-smart /dev/sda; hdparm -B254
/dev/sda; sleep 0.2; done
+ # udevadm trigger --action=change --sysname-match=sda # (also in a loop)
+ # (/lib/udev/udisks-probe-ata-smart /dev/sda &);
/lib/udev/udisks-probe-ata-smart /dev/sda
+
+ and so on, but it seems impossible to reproduce at runtime
+ unfortunately. I also tried those commands while a "grep -r . /usr" was
+ running in the background to induce I/O and disk reading activity.
+
+ The interesting thing is that the bug goes away if you either disable
+ /lib/udev/rules.d/85-hdparm.rules, or udisks-probe-ata-smart in
+ /lib/udev/rules.d/80-udisks.rules. So this seems to happen in situations
+ where there is something reading a lot of files from the disk, and
+ hdparm or libatasmart send their ioctls to the drive.
