[Samba] RE: linux server completely hangs copying files with samba

[Davide Cavaleri]

so, after infinite tries and different combination of bios settings, modules loaded, ethernet adapter i concluded that what makes the system crash is having the ---- usb-ohci.o ----- module loaded; i removed all the modules installed by mandrake and it was ok for at least 100 GB of transfer; loading the usb-ohci.o module even during copying makes the system crash after a time between few seconds and 5 minutes. when it crashes the ide led remains lit, so must be some problem involved with ide as dragan said. making few changes in the bios i had ether card and usb sharing irq 9; i thought was the reason, but letting the ether card have irq 9 and the usb irq 11 was giving the same problem; pratically speaking i don't need usb, so i can leave the module unloaded or even better disable it from bios; but teoretically speaking it would be nice to understand what is going on; with usb-ohci.o loaded it happens only with large transfer rates, so disabling dma is not giving crash; even ricompiling the kernel, which i don't understand why the transfer rate of the ethernet card become slower (any suggestion why?) saves from hangs.
i think i'll sleep anyway and that's what i'm going to do.

david
