I did some additional checking today... On kernels prior to 2.6.22 line, the bug exists and manifests itself exactly the same way. However, when I removed the "-h" flag from /etc/init.d/halt, the drive spins down only once on "Power down" message and there is no sign of the bug and the emergency unload count remains constant. I've verified this on kernels 2.6.21.6; 2.6.20.4; 2.6.18-4-686-Etch. The obvious conclusion is that something must have changed it the 2.6.22 kernels, so that removing the "-h" has no effect. I dunno if my observations are of any value, but I thought You should know...
