sti() called too late. (Erik Thiele)
Unfortunately, some combinations of chipsets, IDE interfaces and drives will not work reliably when interrupts are allowed to occur while we are servicing a disk interrupt. The IDE driver can optionally unmask interrupts during the data transfer, by using "hdparm -u1 /dev/hdx". This is a typical problem; on the one hand, we want to achieve the best possible performance, but once we do this, we might find out that we are no longer compatible with marginal hardware which could have worked if only we didn't try to push it so hard.
