[2.6.0-testX] Problems in EXT3/DM as well as OSST with ide tape in ide-scsi

[Bjoern Brauel]

With the 2.6-test series I have so far hit 2 (for me) quite serious
problems that Im unforunately not able to track down for myself:

1. Using a raid-5 volume under evms2.1.1 (thus not using any evms kernel
code) will cause the kernel to spit out the following after a couple of
days of load on the box:

EXT3-fs error (device dm-19) in start_transaction: Journal has aborted

Volume will switch to ro after that. There's nothing particular that I
can trigger the problem with except that there is always quite a bit of
i/o load once the problem occurrs.

2. Using an Onstream DI-30 in ide-scsi mode with the osst module always
causes the following after writing to the tape (erase/rewind works though):
