I just got a parallel port ZIP drive and have been trying to compile a kernel to support it. I already am happily using an AHA-2940 Ultra in the box. I tried to compile the PPA support as a module, but leave the base SCSI code and the aic7xxx support compiled in. However, when I try to load the PPA module, it screws up the scsi /proc entries and who knows what else.
When I load the PPA module, this happens:
root://$ cd /proc root:/proc/$ cd scsi root:/proc/scsi/$ ls -la total 0 dr-xr-xr-x 4 root root 0 May 7 10:10 . dr-xr-xr-x 18 root root 0 May 7 10:09 .. dr-xr-xr-x 2 root root 0 May 7 10:10 aic7xxx dr-xr-xr-x 2 root root 0 May 7 10:10 ppa -rw-r--r-- 1 root root 0 May 7 10:10 scsi -rw-r--r-- 1 root root 0 May 7 10:10 scsi root:/proc/scsi/$ cat scsi Attached devices: Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: IOMEGA Model: ZIP 100 Rev: D.13 Type: Direct-Access ANSI SCSI revision: 02 root:/proc/scsi/$ cat ppa/0 Version : Curtin 1-08-BETA Parport : parport0 Mode : SPP
Timing Parameters ppa_speed 6 ppa_speed_fast 1 root:/proc/scsi/$ cat aic7xxx/0 Version : Curtin 1-08-BETA Parport : parport0 Mode : SPP
Timing Parameters ppa_speed 6 ppa_speed_fast 1 root:/proc/scsi/$ exit
The aic7xxx entry gets totally baked. I am trying to compile both as modules right now. Is this a known problem? Is it a PPA problem with not handling the different cases of module registration right, or a more general problem affecting any SCSI module that tries to register when there are already SCSI devices compiled in? I'll try to figure it out once I get running again.
Also, (this is totally unrelated) why does upgrading from 2.1.19 to 2.1.36 make login fail on chown of /dev/tty?
