Tests are conducted on a dedicated virtual machine (KVM, architecture
AMD64). No I/O, memory stress. I observe the same problem on a "physical"
debian or ubuntu machine. The string " "Kernel error received" is
immediately returned by 'ipset list'. I just wait a few seconds after the
last 'ipset add' before executing 'ipset list'.

I've just compiled ipset modules provided by your package 6.17 with a
kernel 3.2... And that's much better. Don't know why ?! No more kernel
errors when issuing command 'ipset list'. Unfortunately, the ouput is now
troncated at the first 99 entries.

Yoann.
