I have symptoms where the controler LED is on, the system shows me constant= =20 transfer to (or from) the disk with about 4MB/s and a disk utilization of=20 99%, but no single bit goes over the wire and there's also no other process= =20 which could cause disk activity (also not swapping!). This happens when I transfer large files over NFS to the server (with the=20 3ware). I thought it was NFS but nobody on -current beliefed my description= =20 and a buggy 3ware driver could be a possible explanation for this very=20 strange bug. But o.t.o.h the system was full usable, just NFS locked up.
