Just to add some noise... I had this problem in 2.1.10x.
My system has a DPT 2044 SCSI controller and this exact problem
occured with my Anaconda 4mm tape drive. Unloading and reloading
the driver usually fixed things. I could only get a few hundred
megs on tape before the driver died with a stream of timeout errors.
Now I have 2.1.124 running and have done 2-6gb backups with no trouble
(knock on wood).
I have a Wangtek 5150ES Q250 drive that never worked since the
pre-2.0 kernels and crashed the system in 2.1.107. It has never
been tried with the current kernel (its not even hooked up).
