hi,
I have a dell optiplex gx1 which used to work fine with 2.3.35
but oopsed at startup when I switched to 2.3.47. 48 also has the same trouble.
this is a serial console dump, followed by ksymoops:

which works out (I think) to line 745 in ide-probe.c
sprintf (name, "ide/host%d/bus%d/target%d/lun%d",
hwif->channel ? hwif->mate->index : hwif->index,
hwif->channel, unit, 0);
probably hwif->mate == NULL.
I'd be happy to provide any further information.
thanks,
ganesh
