running a RELENG_7/amd64 as of 2008-Feb-22 with the re(4) driver from the URLs above. As a precaution, I disabled all kinds of hardware offloadings. ...and it is stable for you ? I will defintely go and turn these off in that case! Also, I note your are runnign RELENG_7 and not RELENG_7_0 - any idea what changes there might have been in that ? One of the things I thought about trying was enabling polling, and also possibly turning off MSI and going back to regular interrupts. But these are just wild stabs in the dark as I am assuming that it is losing connectivity due to it losing signaling back to the kernel somehow. WHich is a total guess. After almost one week uptime, the machine is still stable. Before it started lossing packets after very few hours uptime. I'm wondering if this is related to the options I disabled, so I'm interested in your settings. This is extermely interesting! I have applied those settings by hand just now, and will see if it helps. Not quite sure how to get them into rc.conf yet - I am using ipv4_addrs_re0=195.144.8.6/28 195.144.8.4/28 and am not sure how an ifconfig_re0 line might interact with it as yet. I dont want to edit rc.conf in case it reboots... -pete. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Up to I haven't encountered a real show stopper beside the re(4) issues which seem to be fixed at least for my configuration. Nevertheless all those minor glitches which come with a new major release will hopefully be fixed sooner in RELENG_7 than RELENG_7_0. That's the reasone why I don't track RELENG_7_0, but up to now there should be much difference anyway. I think I will track RELENG_7 til RELENG_7_1 will be branched. This is extermely interesting!

Should be oka, to put your primary IP address and the interface options in an 'ifconfig_re0' line and to add additional IPs to the interface using a 'ipv4_addrs_re0' line. At least I've tested it on a VMware and it seems to work just fine. -cs ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
if_re losinbg ability to communicate, even with latest patches
yesterday I had my first experience of an if_re interface simply stopping responding. I ma running 7.0-RELEASE on the machine, but with the lates files taken from here: http://people.freebsd.org/~yongari/re/7.0R/if_re.c http://people.freebsd.org/~yongari/re/7.0R/if_rlreg.h Luckily I had worried about tis and have set the machine up to reboot if it suspects that it';s netowkring is down, so twelve hours later it did so and I can login again. Is there anythign useful I can get out of the logs to try and work out what the problem is though ? A I see lots of messages in the log like this: error sending response: not enough free resources but I am assuming that this is due to the ether stall, not the cause of it. Would enabling polling on the interface help ? (i.e. is this possiblky a lost interrupt issue?). All advice welcome... -pete. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
