System: NetBSD waves 2.0F NetBSD 2.0F (WAVES) #3: Sat Jun 5 23:34:15 CEST 2004 kiers@totoro:/sys/arch/i386/compile/WAVES i386
Architecture: i386

>Description:
After having formatted the disk with one partition and having written
39 GB of data:
fwohci_buf_input: malformed input 1: 12                               
fwohci_buf_input: malformed input 3: 16                               
At this moment [fwohci0] is in the fwohciev state.

Then, after a reboot, during reading the data:
fwohci_buf_input: malformed input 2: 1769
fwohci_buf_input: malformed input 2: 148
Again, [fwohci0] is in the fwohciev state. The machine is usable, 
the firewire disk is not. The process using the disk is in the 
getblk state and can be killed.

NetBSD2.0F kernel on 1.6.2 userland.
