It cpould be the long standing problem we have wrt. disk access. It depends greatly on the chipset / HDD / channel / ... combination used. I saw this with VIA and NForce4 chipsets. My KDE freezes when copying files between ad6 and ad10 (both SATA) and not when copying between any of them the the IDE disks. The standard answer to this in the past has been "it's crappy hardware"; of course, it's seems 90+ of (end-user) hardware out there is included in this category; and it works OK with other OSes. :-/ I have two suggestion that might help: increase the HZ for your kernel and / or your rtc port (if you use it) and use the ULE scheduler. I'd be curious to know if copying the file via rtprio 31 ... helps. -- IOnut
