Console output, 2.6.30.3, fixed tape block size 512k, patch by FUJITA Tomonori
2009-11-19, really this time

Sorry about that. Insufficient sleep, insufficient coffee :-/

Attached is the log when really, actually, using FUJITA Tomonori's patch from
2009-11-19.

The two-fold good news:

a) amflush worked correctly, no EIO, no BUG
I'll still read this tape back in for verification and post a quick comment
about the result.

b) DIO apparently was used: "st0: Number of r/w requests 38867, dio used in
138, pages 17664."
