Subjectoops in 2.4.25 prune_icache() called from kswapd
I have seen the following twice with 2.4.25.  (13 days apart, fairly busy
file server)

Am now running 2.4.26 and will report if it happens again with that.



ksymoops 2.4.9 on i686 2.4.26custom. Options used
-v /usr/src/linux-2.4.25/vmlinux (specified)
-K (specified)
-l /proc/modules (default)
-o /lib/modules/2.4.25custom (specified)
-m (specified)

No modules in ksyms, skipping objects
No ksyms, skipping lsmod
