The examples you cite only support the vice-versa part of your claim, not the primary claim that 16x slots on some motherboards are only for display cards. Do you have a reference for that? You're not being thick. I'm simply using what's in the manual as a hard, validated example that the *type* of card that goes into a PCIe x16 slot can matter, and that some types are compatible while others are not. I cannot find you a hard documented reference for my claims right now, so you can consider them lies/FUD/whatever for the time being, that's fine by me at this point. I can find you examples on Google of people who invested in Areca ARC-1220 cards (PCIe x8) only to find out that when inserted into one of their two PCIe x16 slots the mainboard wouldn't start (see above). I can also find you examples on Google of people with Intel 915GM chipsets whose user manuals explicitly state the PCIe x16 slot on their board is intended for use with graphics cards only. Just trying to understand; I think I can recall reading about issues with the 915 chipset. I agree a check, don't assume warning is reasonable.

UDP Packet reassembly
Hello List, Could someone enlighten me as to when FreeBSD 6.3 does UDP packet reassembly? I am having a problem where I am getting a fragmented udp packet (2 pieces) everthing is fine if I get the first frag first. but if the second frag comes first then both fragments get dropped. I am using ipfilter and a bimap to redirect these packets to a host inside of the FreeBSD box, so I suspicion it is ipfilter causing the drops. I know, I know 6.3 is ancient history, but any insight would be appreciated. Thank, Steve -- They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety.

Normally, reassembly is performed on the destination host, but routers or firewalls along the path conceivably might also reassemble packets.

It's probably the firewall dropping the traffic, yes-- running tcpdump on the firewall versus the destination host would confirm this. Something like keep frags on your pass rules would help if it is ipfilter...

Re: recommendations for laptop and desktop
heh, the dv-series really nice exterior, but, inside, poor choices in cable routing, increased use of polymer ribbons prone to breakage and open circuit from even a single disassembly (lint/dust is the #1 laptop killer, they have to be cleaned out regularly, no less than twice a year in most environments), undocumented screws and chinese finger puzzles, undocumented cables, incorrect instructions, parts that don't exist, parts that exist but aren't documented, incorrect part numbers Interestingly, my primary laptops (two of them for me, and one for the lady) are Compaq C-300 series (upgraded to the 945GM motherboard and T7600 65nm Core2 Duo) are reliable to the extreme, well-documented (except for that one screw with the silk-screened arrow pointing at it in the upper left of the mobo), a complete airpath cleaning with practice can be done in about an hour with three screwdrivers, a muffin tin, pad and paper (which screws in which muffin hole), a toothbrush, unscented toilet paper (wipe the silicon to a mirror finish again), and arctic silver 5. The series is also labeled as the HP G-3000 series. The Compaq C-500 series is in the same chassis with only minor changes. The problem lies in that most of these were sold with the 940GML chipset (Celery only), but 945GM was an option and those mobos are about $100 USD +- $30 USD on eBay, mostly HannStar refurbs from China. These were introduced in 2007, and must be flashed to the most recent BIOS before putting in a Core2 Duo T7200 to T7600. My only complaint under BSD has been the Mini-PCI has bad ACPI, as the broadcom and intel driver both will panic the system at the worst, or at minimum refuse to load the driver with a could not allocate resource. No biggie, it works under winblowz xp and 7. Under BSD, just use a USB wifi. Interestingly, under SuSE, the NDIS driver for the broadcom wifi does work. Conclusion: Get a Compaq C-300 or C-500 series system, preferably non-working (most likely a 940GML/Celery anyway), put in a good 945GM replacement board, and you will have a reliable, reasonably recent, low-cost laptop, just remember to clean it out when idle is in the mid to high 70's Celsius. The newer dv-series laptops are slick and all that on the outside, and very tempting when you play with it at the store, but they were made with the intent that people throw them away instead of having regular maintenance performed (cleaning), based on the number I have repaired, all needing new motherboards. Don't spend $800-1500 on a laptop that will fail in a year or two and be that hard to clean without having to buy replacement parts (ribbons, cable bundles, etc). STAY AWAY FROM HP dv-ANYTHING ESPECIALLY!!! THE AMD VERSIONS ARE EVEN MORE PRONE TO FAILURE!!! Chip Camden wrote: Quoth Jim Bryant on Thursday, 14 July 2011: stay away from newer hp laptops. been repairing laptops for money in recent years. HP laptops made after 2008 generally have serious issues with BGA lifting, and usually require motherboard replacement after 1-2 years. also their manuals have even more undocumented disassembly instructions, as well as incorrect disassembly instructions (use common sense and your eyes, following instructions will destroy hp laptops). Another data point: I bought an hp dv9000t in 2007, three years later the motherboard died. I agree with avoiding HP. I like my ASUS K72F, except that the Ironlake graphics aren't yet supported (soon, right Kostik?) ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
