Hi all,

Still gnashing my teeth over this HP Colorado drive. Found some pointers 
which suggested disabling DMA -- have done so for both drives on that 
controller. Got 3 successful dumps since Thursday (>3GB written).

The problem today is as follows. The dumps failed with an "Input/Output 
error" after 299kb written. When amcheck ran (without changing the tape) it 
failed before reading the tape. My logs give me:

Can I be sure that those IRQ timeouts are due to a faulty device? Can there 
be another explanation?

Regards,

Brian Jonnes
