Comment 3 Chuck Ebbert 2007-11-21 20:11:08 UTC
Looks like this is needed:
libata: increase 128 KB / cmd limit for ATAPI tape drives

Plus these not-upstream ones:
[PATCH 1/2] libata: workaround DRQ=1 ERR=1 for ATAPI tape drives
[PATCH 2/2] libata: use ATA_HORKAGE_STUCK_ERR for ATAPI tape drives

And maybe more?

Comment 4 Alan Cox 2007-11-21 22:01:12 UTC
DRQ/Stuck err should be sufficient. The other is a performance item but should
go in too

Fixes are in F8 kernels starting with

Comment 7 Craig Goodyear 2007-12-13 16:11:17 UTC
I have installed kernel  The ide tape drive 
now appears to fucntion correctly.  I am able to use the mt
commands to query and position the drive.  Tar now works to 
read from the drive and write to the drive.
