Hi I'm experiencing reproductible oopses on my stock 2.2.19 (with BadRAM patches, though I seriously doubt thet can affect described behaviour). The system is Slackware-current, kernel compiled from sources, on Pentium 120 with 32Mb RAM. The oops report is from mc but any process trying to read from /proc/net/ip_masq/app causes the oops. I suspect it may be caused by the ip_masq_netmeeting (by Alex Nicolaou, http://www.cgl.uwaterloo.ca/~anicolao/) module I inserted for a short while and then removed from the kernel, but I'm not sure as I'm not a pro kernel hacker ;-). Currently the output of lsmod looks like this: ip_masq_user 2768 0 (autoclean) af_packet 6144 0 (autoclean) ip_masq_portfw 2688 1 (autoclean) ip_masq_ftp 3808 0 and ipmasqadm portfw -l has one redirection: TCP xxx.yy.zzz.www 192.168.2.2 6699 6699 10 10 If you want more details please CC the reply to me as I'm not subscribed to linux-kernel, though I'll try to keep up-to-dat with replies and respond appropriately.
