Ok, I think now I have the latest:
arc# uname -a
FreeBSD arc.pmp.uni-hannover.de 5.4-STABLE FreeBSD 5.4-STABLE #3: Mon Apr
4 11:21:26 CEST 2005
I can attach the drive now, and it basically works. I can successfully do
something like this:
(%:/mnt/xs-drive)- dd if=/dev/zero of=Z bs=1024k count=10
10+0 records in
10+0 records out
10485760 bytes transferred in 3.841036 secs (2729930 bytes/sec)
However, when I increase the amount of data by using count=100, the thing
hangs again. This time I get the following:
(%:/mnt/xs-drive)- dd if=/dev/zero of=Z bs=1024k count=100
umass0: BBB reset failed, TIMEOUT
umass0: BBB reset failed, TIMEOUT
[...]
Any hints?
