I cannot read anything from my tape (Tandberg DLT8000, LVD
interface, ID=5) connected to an aic7899 or an sym53c895 using
kernel 2.4.3-XFS or 2.4.7-XFS. (Everything works fine on
2.2.16.) Loading of st.o works. stinit works. mt (status, tape
positioning) works. But when I try to read the amanda header
from the tape (dd if=/dev/nst0m bs=32k count=1) I get the
error
dd: reading `/dev/nst0m': Cannot allocate memory
The syslog says:
Jul 29 17:49:28 depp kernel: sym53c895-0-<5,*>: FAST-10 WIDE SCSI 20.0MB/s (100.0 ns, offset 15)
Jul 29 17:49:28 depp kernel: st0: Block limits 2 - 16777214 bytes.
strace gives something like:
...
open("/dev/nst0m", O_RDONLY|O_LARGEFILE) = 0
...
read(0, 0x8052000, 32768) = -1 ENOMEM (Cannot
allocate
memory)
...
Nearly the same for tar (with default block size of 512 byte).
BUT: if I use bs=64k it works!!?
TIA
