Alan and All, I've detected a bug somewhere in 2.4.0-acX, at least in ac4, the first ac kernel I built. It seems that I can't mount a scsi zip disk in, unless the following has occurred: 1. There is a disk in the zip drive when I boot. 2. I fdisk the scsi block device and re-write the partition table. (I accidently discovered this). in other words I get this: mount: /dev/sda4 is not a valid block device. If I try to insert a zipdisk and mount it after I boot up. This problem does NOT occur as late as 2.4.0-final. Specifics of my system: The SCSI board is a real cheap SYM810A based Fast SCSI-2 PCI board. I use the sym53c8xx driver built in, as is scsi disk support. The only thing I use the scsi board for is the external zip 100 drive. It still occurs in ac6. (I've only build ac4 and 6). Here is the specifics from a dmesg of 2.4.0 booting: (2.4.0-ac4 and 6) is the same.
