Hua Zhong ce42f19137 [PATCH] IDE error handling fixes ... In 2.6.15.1 I encountered some IDE crashes when unplugging IDE cables to emulate disk errors. Below is a patch against 2.6.16 which I think still applies. 1. The first BUG_ON could trigger when a PREFLUSH IO fails (it would fail the original barrier request which hasn't been marked REQ_STARTED yet). 2. the rq could have been dequeued already (same as 1). 3. HWGROUP(drive)->rq could be NULL because of the ide_error() several lines earlier.
