Package: linux-2.6 Version: 2.6.32-41 Severity: normal The system does hand under heavy load, like cp -ra bigfolder or tar czvpf bigfolder. After the IO intensive task completes or is killed, system (and by system i mean web/sql/.. servers) continue to work. Changing priority with ionice or nice, doesn't help. If i boot using kernel from Lenny, no such problem occurs. But that it's not an option anymore, because i use aufs kernel module and userspace tools from Squeeze are not complatible with Lenny's aufs kernel module. If more info is needed, i can provide it. Just ask.
