I have noticed strange messages in my logs. Here is a snip: May 27 11:09:59 [kernel] printk: 6 messages suppressed.

And i have no idea what smp has to do with this. There are also strange messages about nf_getsockopt and ip_getsockopt. I don't know if they are related to the kernel and(or) squid (zero-penalty-hit flag). Squid doesnt crash. This is strange. Kernel 2.6.11-gentoo-r8 is patched with esfq patch, connbytes and connlimit (patched not to crash the kernel) from pom. Reproducible: Always Steps to Reproduce: 1. 2. 3.
