Looks like this is a deliberate test for unknown requests that was added in
2.6.31 with the following commit:
commit 2c7eaa43c3bb7b3b9fe2051d17f308c1f0728c78

ide: BUG() on unknown requests
Unsupported requests should be never handed down to device drivers
and the best thing we can do upon discovering such request inside
driver's ->do_request method is to just BUG().
In previous kernels the code would not dump, but still fail and print the
request flags, identified by "ide_do_rw_disk - bad command", to the kernel
log.
Manty: Have you ever seen such messages with previous kernels?
Question for IDE maintainers: should maybe the old printing of request info
be reinstated, or can the request flags also be obtained from the BUG
info?
Cheers,
FJP
