Hello.

While writing to a tape drive unit I get this kernel log:

(sa0:sym1:0:5:0): Invalid request.  Fixed block device requests must be a multiple of 1024 bytes

Can anyone explain what this means?

OS is FreeBSD 4.6.2-pl2, backupsoftware is afbackup 3.3.7pl3, tapedrive unit is
a HP SureStore 40x6i (DDS-4 autoloader with 6 cartridges). By default, the tape
drive shows up after reset this 'mt status' messages:

Mode      Density              Blocksize      bpi      Compression
Current:  0x26:DDS-4           1024 bytes     97000    DCLZ
---------available modes---------
0:        0x26:DDS-4           1024 bytes     97000    DCLZ

2:        0x26:DDS-4           1024 bytes     97000    DCLZ
3:        0x26:DDS-4           1024 bytes     97000    DCLZ
---------------------------------
Current Driver State: at rest.
---------------------------------
File Number: 1  Record Number: 0        Residual Count 0

This is hardcoded by DIP-switches and it whas worked up to FreeBSD 4.6-RELEASE.

Any ideas whats wrong?
