I was having power source failures on my neighborhood, and I was not having
time to test it, today the Company was replaced the transformer and I cant
test it now.
Let me see, the patch of course does not apply, but I can figure out how to
proceed on kernel 2.6.16.
But guess who, not Device busy as error, of course and NO BAD SECTORS With
pktcdvd UDF.
:)
Txs, do you think this modification I can use without care on Sata o other
devices going trow SCSI?, cause I be wonder if this could be into main kernel
line.
