Re: Question regarding Intel ICH7 motherboard and integrated RAID
I have the BIOS set to IDE mode; I found the other problem "the hard way" and the workaround...

It definitely is a problem with the ICH7R and 6.2-STABLE on an ASUS P5W DH. Note that it actually does work but the performance hit is unbearable. Whatever it is about AHCI mode causes about 37,000 interrupts per second per vmstat -i, knocking the entire system performance down by about 50% on a Q6600 pushed slightly (eg., 16 minutes to -j20 buildworld vs. 11 minutes to -j20 buildworld with IDE "compatibility" mode). I don't believe you'll have any trouble with a geom managed RAID array if your Gigabyte can support the IDE "compatibility" mode for the ICH9, I'm using a variety of geom providers here simultaneously through the ICH7R without any problem whatsoever in that mode. The hit may not even be noticeable since compatibility mode takes the interface down to 150MB/S SATA-I and common 7200RPM drives don't seem to be able to sustain more than about 70 or 80MB/S. > > I need to be able to dual-boot Win XP on the machine, so my plan was > to get 4 320GB drives (later expanded to 6), put them into RAID10 > array and that way get good redundancy and performance in both > operating systems.

I'd recommend two drives to the XP and your old motherboard, two to your new system with the Q6600, resulting in an XP gaming and media system up 24/7 while you're getting your serious work and internet stuff done on the CURRENT machine, but that's just me ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I'm about to get Gigabyte's GA-P35-DQ6 motherboard (also with Q6600) and was planning on configuring RAID10 array using the on-board ICH9R chipset. Are you saying that this doesn't current work (on 7-CURRENT), or that there are performance issues with such setup? I need to be able to dual-boot Win XP on the machine, so my plan was to get 4 320GB drives (later expanded to 6), put them into RAID10 array and that way get good redundancy and performance in both operating systems.

There's a known issue with an interrupt storm when the ICH7R is configured for AHCI or RAID, and a pr was filed back in July(don't have the number, search for interrupt storm on atapci1+). The suspicion was that some peripheral no one has identified yet is hammering the apic and we can't mask it. The workaround is to set the BIOS for IDE mode. It's a bit of a drag because SATA-II mode isn't reached when in IDE mode, only in AHCI (and RAID?) mode. If you don't panic when you set it for IDE mode then you've probably run into the same problem. On the plus side FreeBSD on the Q6600 *rocks* and our geom stuff does the RAIDdy stuff nicely for a software solution.

Most likely your RAID BIOS wants to enter protected mode. BTX normlly runs in vm86 mode. Please do transcribe and post here so others may help to debug. kib has real mode BTX code which hasn't gone in to the tree yet.

On the BIOS probe it just shows up as a disk; I tried it as a "JBOD" single disk and also with the RAID feature shut off entirely, so its just a disk adapter according to the BIOS. If there's a disk plugged into it, with all the fancy-schmancy RAID stuff turned off, it blows up BTX instantly when I hit "F1" to boot from the first disk. It is, in that configuration, the FIFTH disk (and has no partitions on it - so its not a matter of it trying to boot Winblows or something like that) I can't get a dump easily since of course it happens right from the boot process, so there's nowhere for it to dump TO.

Possibly a bug in BTX.. without the dump info it can't be debugged though.. Could be a buggy BIOS too.

Question regarding Intel ICH7 motherboard and integrated RAID controller
Hi folks; I have a new Intel ICH7 board here that has Quad-core support. It works well EXCEPT It has an on-board RAID controller with some internal buffer memory. I'm not all that interested in using it as a RAID adapter. I am, however, interested in using it as a disk adapter, as a way to both spread load AND benefit from its cache memory. Unfortunately, BTX panics if I attach a disk to it! I have no idea if FreeBSD would see the disks as just "normal" "ad" disks, as I can't get anywhere near that far to find out... Any ideas?
