there are also patches for things that are really broken. :-)

SuSE 10.0 should be generally stable in a month or so. :-)
It appears stable x86 generally but still spits the dummy on my
AMD64 laptop when "stressed".

Indeed. IIRC, SLES supports iSCSI which provides another option for
interfacing to the LTO; by putting it in a special system running
the "latest" kernel (of a "free" distro) just for that purpose.
That, btw also provides the flexibility of using the LTO easily from
other Linux servers; as long as you have enough gigabit (TOE) NIC.

It is somewhat surprising that you do have sporadic behaviour with
LTO... have you asked about this on the sles-e mailing list?

I wouldn't build a new system based on a 2.4 kernel. I don't
particularly enjoy the disruption of system upgrades so the further
apart that they can be, the better.
