It's not the aic7xxx driver that's causing the problems: We have just been through the same problem this week. 2.2.14 does indeed support the 789x, including the 7899 but: Dell are '...using two Northbridges which messed up PCI device detection and another problem that messed up the IO-APIC in the kernel.' I'm quoting from the person that got us fixed up with patches and a boot disk. Dell UK have not been very helpfull so we had to turn to US help. I am using Slackware 7 and I'm waiting for clearance to publish the patches or see if someone else can. I don't know what the game is but Dell UK said 'we have our own kernel...' which really stinks unless they make their patches open source (it's possible they are but we simply haven't been able to verify that and it's now a long holiday weekend here so everywhere's closed). Neither patch is for aic7xxx.c which does its job as nicely as ever. They are for: include/linux/pci.h and arch/i386/kernel/io_apic.c The patches go into 2.2.13 and 2.2.14 cleanly but both seem to be originally for 2.2.12 so that will probably be OK as well. The peer bus scanning stuff is looking for busses behind north bridge chips. Sorry to be cryptic here but I just don't know how the licensing works out with this. I'm realize that the GNU license part 2 b) means that that if I'd received this stuff together with the rest of the kernel I could just post it but I'm not 100% sure of it's origin..... I suspect that this Dell configuration may appear in other boxes but I don't know for sure. If anyone has knowledge of the 2450 I'd like to hear about it as we have one to set up in 10 days (also has 7899). We have the 4400 running OK but with U 160 IBMs we didn't get it to boot with lilo from the superblock yet (no time left to try anything else until next week).
