Linux SCSI Error Question with SG Driver

[Justin Piszcz]

I have a tape library connected to a Linux box here and every once and a 
while I see these in dmesg:

sg_low_free: bad mem_src=0, buff=0xdb6a8000, rqSz=32768
sg_low_free: bad mem_src=0, buff=0xdb6b0000, rqSz=28672
sg_low_free: bad mem_src=0, buff=0xdb738000, rqSz=32768
sg_low_free: bad mem_src=0, buff=0xdb718000, rqSz=28672
sg_low_free: bad mem_src=0, buff=0xdb680000, rqSz=32768
sg_low_free: bad mem_src=0, buff=0xdb678000, rqSz=28672
sg_low_free: bad mem_src=0, buff=0xdb670000, rqSz=32768
sg_low_free: bad mem_src=0, buff=0xdb668000, rqSz=28672
sg_low_free: bad mem_src=0, buff=0xdb660000, rqSz=32768
sg_low_free: bad mem_src=0, buff=0xdb658000, rqSz=28672
sg_low_free: bad mem_src=0, buff=0xdb650000, rqSz=32768
sg_low_free: bad mem_src=0, buff=0xdb648000, rqSz=28672

Does anyone know what they refer to?

A quick google and newsgroup search just turn out the actual snippets of 
code that produce these errors, thanks..

Justin.
