[Note: I careated Bug #29968 in linux86 (Ubuntu), because launchpad
failed to bring up this bug when I searched for it by keywords, & the
old (from bugzilla) bug #.  Having found this page for my bug, I'll put
the comments about this bug here.]

CURRENT DAPPER (prerelease) WORKS OK.

Basically, BenC told me to try Dapper. After much delay, for getting a
dapper that would boot from my cd, I did try the prerelease of Dapper.

Result: The bug doesn't occur in Dapper prerelease.
(I tried three times to copy the 10GB file, each time it copied properly, & the drive did not get disconnected.  Each time took about 17 minutes.)

I only know Dapper prerelease works, but don't know what caused the fix.
Was it the kernel? Some other support sw? Drivers for firewire? SCSI?
Something else???

This is a bad bug to have, because files can get corrupted &, since this
bug is not easy to notice unless you are looking for it, the corrupted
files might not be noticed until it is too late to recover important
data. Bad.

So, BenC, what should be done to fix Breezy?

Put the Dapper linux kernel into Breezy???

Backport some changes from Dapper to Breezy?
