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

[Davide Cavaleri]

final experiments;
after realizing that unloading the usb-ohci module (non even the usbcore) system was fine, i compiled the kernel without modules support and without usb. the machine crashed and actually i was really angry, becuase i thought i had found the problem; but finally i discovered that if usb is not loaded the machine crashes, but if i load it and unload it (going back to the same situation) it doesn't crash. obviously if i disale usb from bios everything in ok. maybe is something about irq, so if it is enabled in bios the ira (11 for me) is used. loading and unloading the module will do something strange to the irq handles. cat /proc/interrupts gives 0 on usb.
at this point i'm curios to find out why this happens; since i've red of many people having this problem maybe someone (not you, as you told me) had a similar situation.
don't know if it's relevant, but only once the keyboard was blocked, i had to unplag and plug it back (ps/2 keyb) and it was ok, checking the interrupts they had jumped from 1500 to about 3000 in few seconds.
going to work, nice day
