If a program dies and leaves commands hanging on the generic scsi
interface, Linux 2.0.27 has a tendency to barf bigtime.
This is easily reproduceable.
Does anyone know how to get debugging information out of modules? I don't
want to have to recompile a monolithic kernel just to get symbol
information or use gdb.
scsi0: data overrun of 29 bytes detected; forcing a retry.
