High!
I have also a problem with a "sleeping device": A EZFlyer (230MB) attachedd to my external SCSII-Bus (NCR53x810). After removing a media from the drive and wating for <n> minutes, I cannot access the drive any longer. Sometimes it would help to re-insert the media several times until sthe drives wakes up (you can hear click--clack--clack from the read/write heads then. Often I have to reboot. The first time before I recognized what's going on I hang the kernel by mounting the sleeping Flyer. No timeouts! But I think, there should one be implemented?!!
Is there a chance to reset the SCSI-Bus for scanning all devices a second time?
I am still using 2.1.13...
KEEP HACKING! meino ...who dances with modems...
