Just spent the better part of 4-hours trying to patch my 6-RHEL 6 servers
with issues caused by the latest kernel (we are required to patch to the
latest, every month) and the latest lin_tape driver.

RHEL 6 KERNEL=2.6.32-696.el6.x86_64  -  lin_tape 3.0.16 would not rpmbuild
successfully.  Fails with:

*make: *** [bldtmp/lin_tape-2.6.32-696.el6.x86_64.ko] Error 2*
*error: Bad exit status from /var/tmp/rpm-tmp.PGuVC0 (%build)*

*RPM build errors:*
*    Bad exit status from /var/tmp/rpm-tmp.PGuVC0 (%build)*

So, went out looking and found lin_tape 3.0.18.  No mention of kernel
compatibility updates (as previous levels have said) and the 2-changes in
the readme didn't sound like anything I needed/wanted and was
engineering-speak, anyway.

While lin_tape 3.0.18 rpmbuild's clean/no errors it introduces a new
problem/error.

ANR1819E Permission denial to device /dev/IBMchanger6.

After finding docs on the permissions error that said to chmod r+aw to the
/dev entry (which got rid of the "permissions" problem - never had to do
that before), still got all kinds of errors and TSM server "internal
failures" and it telling me the library needed auditing, etc.

So we have backed off both the kernel level and lin_tape driver level!

Anyone else have these kinds of adventures with lin_tape?
