Um, it *does*, as of 0.84. Well on my test box (RedHat 7.0 with many Rawhide components, including Rawhide kernel 2.4, Rawhide kudzu) it does not. I have my zip drive (ppa module) listed as a scsi_hostadapter entry in /etc/modules.conf, but kudzu still doesn't load the module, nor detect the zip drive. I tried to setup the system to use the initrd to load the module, but ppa has dependincies that need to be included for it to work - dependincies that arn't an issue if the modules are loaded after the system is properly stated. I can only get kudzu to detect it if I manualy load it before kudzu starts (/etc/rc.modules). As to recurcive lookups on detected devices, that was a particular probem with an earlier (RH 6.2) version, but I did check the change-log. What version of kudzu do you have installed? kudzu-0.89-1 downloaded and recomplied on my RedHat 7.0/Rawhide-updated box. What's your /etc/modules.conf look like? /etc/modules.conf alias eth0 ne2k-pci alias parport_lowlevel parport_pc alias usb-controller usb-uhci alias scsi_hostadapter ppa Sorry about the delay. What happens if you just run 'modprobe ppa' from the command line - does it work, or does it require other stuff (parport?) configured separately? Basically, kudzu blindly does 'modprobe scsi_hostadapter' and assumes it will work, or if it doesn't, that there isn't anything it can do about it. 'modprobe ppa' and 'modprobe scsi_hostadapter' run as expected. When run in /etc/rc.modules it also runs as expected (so its not a boot order thing). OK, I'm confused. If you run 'strace -fo <some file> kudzu -s', does it appear to be forking and running modprobe? Created attachment 9200 [details]
Strace of kudzu as requested
I've attached the strace, as I can't see the fork - but I may have missed it. Oops, that logic is really screwed up. If you rebuild with the attached patch, does it work better? Created attachment 9263 [details]
patch to fix kudzu module loading
Never mind, it's more complicated than that. Ugh. OK, take two. This appears to work here; basically, if we're keeping track of which modules kudzu loads, so we can remove them later, we need to deal with actual module names, *not* aliases. Created attachment 9279 [details]
new patch. Should work much better.
To clarify, use the second patch *instead* of the first one, not on top of it. This should be fixed in kudzu-0.93-1; please reopen if the patch doesn't work for you (it works for me, but I'm not testing it on a system with a ppa adapter.) |
