Hi,

recent kernels 1.6ZI..K give me an endless flow of 

sd0(mpt0:0:0:0): adapter resource shortage

on the console during heavy disk access, especially with softdep enabled
on filesystems.

In the latter case, I also get the occasional

sd0(mpt0:0:0:0): adapter resource shortage
sd0(mpt0:0:0:0): adapter resource shortage
/var: got error 16 while accessing filesystem
panic: softdep_deallocate_dependencies: unrecovered I/O error

and, when I try to break into ddb (serial console), a
