APA-1480 problems: maybe reset?
|
I use an Adaptec APA1480 CardBus card on an Apple PowerBook 2000, running LinuxPPC with a 2.2.15pre13 kernel and pcmcia-cs.25-jul-00. Up to now, I tested a scsi disk at 20 MB/sec, an old Exabyte 8505 tape drive at 5 MB/sec, and a new Exabyte Mammoth tape drive at 10 MB/sec, and I experienced a quite odd behaviour.
If I switch the device on, wait for a long time until the "internal" reset sequence is finished and insert the card after that, then no scsi device will be found. If I insert the card during this sequence (e.g. as long as the disk activity led is on), then the disk and the Exa 8505 are recognised, but the Mamooth gives a number of odd messages in /var/log/messages (see below). I suspect that something with the scsi reset sequence upon card insertion failed. Any ideas? Thanks for your help, Albrecht.
