Hi all.
I like to rereport that the IDE Controllers get strange device- node-number in Linux-2.4 (currently vanilla 2.4.16) at least using DevFS.
I reported (~a year ago) that when I disable the primary channel of the on-board controller of the Asus-K7M (Irongate based) the second channel will be host1 - no host0 can be found.
My today's issue is our K6-2 based server with an Gigabyte Ali-Aladin5 board. The on-board controller is host0 but the additional Promisse TX2 Ultra100 will be host2 ??? no host1 there ... :
server1:~ # l /dev/ide/ total 0 drwxr-xr-x 1 root root 0 Jan 1 1970 . drwxr-xr-x 1 root root 0 Jan 1 1970 .. drwxr-xr-x 1 root root 0 Jan 1 1970 host0 drwxr-xr-x 1 root root 0 Jan 1 1970 host2

It is really odd to see the Linux kernel mangling this different on each Workstation ...
