Subject: mvsas: blocked task on writing to tape
Date: Thu, 19 Aug 2010 13:34:56 +0000 (UTC) [thread overview]
Message-ID: <i4jbu0$icb$2@dough.gmane.org> (raw)
hi
recently upgraded the kernel from 2.6.32-bpo.4 to -bpo.5 on Debian Lenny.
Since then, the tape drives don't work anymore. after some time writing
to tape, it stopps working.
I then compiled a vanilla 2.6.35.2 kernel to verify that the
problem still exists - and it does (log below).
debian kernel 2.6.32-bpo.4 is IMHO 2.6.32.11+patches
debian kernel 2.6.32-bpo.5 is IMHO 2.6.32.15+patches
Hardware:
*Areca ARC-1300ix-16 (mvsas)
* Quantum LTO-4 tape drives connected with SAS (1x standalone,
1x SuperLoader3 with Drive) - both having problems.
