Perhaps I'm being thick, but this says "a 16x slot on this board does not support a display card" not "a 16x slot on this board only supports a display card." 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.

Did you try a non-graphics card in the slot to see what happened? Saying "The 16x slot is where you put the graphics card" is probably not unreasonable for 99% of the users of that board.

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". > > And up until last week I owned and used an Asus P5Q SE (P45-based with > > ICH10 SB) board, so I can refer you to the fact that the P5Q Pro user > > manual "hints" that the PCIe x16 slot is for graphics only but doesn't > > downright say that. > > Did you try a non-graphics card in the slot to see what happened? Saying "The > 16x slot is where you put the graphics card" is probably not unreasonable for > 99% of the users of that board. No I did not. Let's recap my point because this will be my last reply on the matter: If your motherboard only has PCIe x16 slot(s) available in it, and the user manual doesn't say anything about the slot(s) being usable for non-graphics purposes, BEFORE shoving a non-VGA card in the slot, be sure to consult your user manual and the motherboard vendor to ensure the card will work. The assumption within the industry appears to be that PCIe x16 is "intended for VGA adapters", even though on an engineering level we all know there's no reason (other than design limitations of the board or chipsets) that non-VGA adapters can't be used. I can't explain to you how or why this limitation would come into play, but it obviously can, as the Supermicro board examples I provided are hard evidence of some boards and configurations discriminating based on what type of card goes

The ps output makes it not very inplausible that the reporter got the LOR between vnode lock and page busy flag. The correct order is vnode lock -> busy bit. vmopar is a wait for the busy page state. Mentioned revision does not change the lock order. Anyway, this is only a speculation, until the requested data is provided. pgpN7hsFvpj0G.pgp Description: PGP signature
dtrace/mysqld
If anyone interested - i was able to compile dtrace support in mysql-server55 port. During this i found a bug in dtrace/bsd - if it is running more then 1 time on the same object (this is the case for mysqld) then object is broken. I was able to do workaround (with preserving original object and then copying it) and then everything compiled and started correctly. This is an example: bsd# ./work/mysql-5.5.14/support-files/dtrace/query-time.d dtrace: buffer size lowered to 2m Who Database QueryTime(ms) root@localhost mysqlselect sleep(1) from user limit 11000 root@localhost mysqlselect * from user limit 1 0 I will try to cleanup my patches (its currently very dirty hacks) and submit them to the mysql bugtracker (and port). Feel free to contact me if you want to test this (or to fix dtrace/obects bug). ___ 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"

I'm not unique, many people have success doing this. Once in a blue moon, an intelligent board manufacturer puts comments in their user manual to the effect of "the PCIe x16 slot is only to be used for VGA adapters and will not work with non-VGA cards", or vice-versa. Here's some hard evidence of my claim: Supermicro X7SBA server-class motherboard user manual has the following line in it: "Note: The Intel 3210 chipset does not support add-in graphics cards in the PCI-E interface provided by the Memory Controller Hub (MCH)." So in that boards' case, the PCIe x16 slot (which only has PCIe x8 worth of lanes wired) will work with controller cards but not VGA adapters. And here's another, for the X7DVL series boards: http://www.supermicro.com/support/faqs/faq.cfm?faq=10582 "This is a server board, and you cannot place a x8 or x16 VGA card on this board. Only onboard VGA is possible. If you need to place a VGA card please use X7DA(x) board". And up until last week I owned and used an Asus P5Q SE (P45-based with ICH10 SB) board, so I can refer you to the fact that the P5Q Pro user manual "hints" that the PCIe x16 slot is for graphics only but doesn't downright say that. TL;DR -- it varies from board to board, ask your motherboard manufacturer whether or not it'll work *before* just jamming a card in there. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.

Re: SATA 6g 4-port non-RAID controller ?
> Jeremy may not have seen PCI express x16 HBAs working on consumer > boards, but I have, plenty of times. Ditto. Indeed, I wasn't aware you could do anything to a PCIe slot to prevent it working. Have seen motherboards which wont *boot* from an HBA in a PCIe slot, but never one which couldnt use the card when plugged in. I generaly use MSI boards, and all of tose have taken PCIe controllers quite hapily - inclduing booting off HP/Compaq SMART RAID controllers which do have a reputation for being fussy outside of HP machines. Am currently using a variets of Silicon Image based eSATA controllers on the same motherboards. -pete. ___ 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"
