[1.] System lockup while trying to write to Fujitsu MO drive (640MB IDE interface) [2.] This works under RH7.0. Here's that I do: insmod ide-scsi ; SCSI emulation needed here mount /dev/sda /mnt/MO ; mount the drive ls -la /mnt/MO ; see is anything's out there cp .bashrc /mnt/MO ; Copy a file and watch it lock up tight This works just fine in RH7, but dies miserably with kernel 2.4.0. If there's any additional information that you need, let me know...
