As a matter of = upkeep/security, I cvsup them and go thru the buildworld, kernel, = mergemaster, etc; haven't had much problem. In the last couple of months, upgraded to 4.6 and 4.7 using RELENG_4 = with again no errors, however, now under a light smurf attack, I get: panic: icmp_error: bad length syncing disks... 1 done Uptime: 1h12m58s Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... I have found couple of posting on FreeBSD sites, google, dogpile, etc = pointing to a patch for netinet/ip_icmp.c which seems to have been = incorporated into the 4.6 tree; not sure though. I have tried building the kernel with RELENG_4_7 to no avail still = panics.=20 Also tried to down rev the kernel to 4.4, 4.5 using the kernel file on = the same machine that I had saved prior to upgrade, which is holding up = better, but still panics frequently. Hardware: Dell PowerEdge 350, 2 built-in Intel nic cards, 256 meg of ram = and only doing ipfw.=20 The kernel is built with options BRIDGE. Don't know what other info you = might be interested. Deeply appreciate any help or info.=20 Regards, Patrick Soltani To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
