For some strange reason the on my TYAN MPX Baord the SB-Life always has
own interrupt. While the BUZ always shares it's interrupt with the 3Com
905 and es1371 devices.
I've found that it depends on the slot you put it in. Counting from top PCI slot, I've got the Buz in slot 3 (first 32/33 slot), and the soundcard in slot 5. (One from the bottom). This gives me:
CPU0 CPU1 0: 4252472 4275870 IO-APIC-edge timer 1: 21649 22532 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 8: 1 0 IO-APIC-edge rtc 9: 0 0 IO-APIC-edge acpi 12: 154818 155231 IO-APIC-edge PS/2 Mouse 14: 70056 68148 IO-APIC-edge ide0 15: 1 11 IO-APIC-edge ide1 17: 2070 2134 IO-APIC-level Buz[0] 18: 3156661 3116437 IO-APIC-level YMFPCI, [EMAIL PROTECTED]:1:5:0 19: 1136809 1158061 IO-APIC-level usb-ohci, eth0
Maybe, I'm not really conviced about that. The main problem is/was the pico - bridge I think. A not really good pice of HW. The IC's used on the BUZ are not really differnet from that one used on the other card. Some are even better that.
Oh. Okay.
I'm just testing the bttv card (Hauppauge Win-TV). And the card works quite fine. No lost frames in 10 Minutes. Each CPU's has a load of about 15-25% at PAL full size recording. :)
The command I use:
lavrec -f a -i P -g 720x576 -q 80 -s -l 70 -R l --software-encoding test03.avi -U --file-flush 10
I couldn't even watch on the Zoltrix TV Max. A bunch of IRQ errors and a then a freeze, using 0.7 or 0.9 drivers. Whuch drivers were you using for the BTTV?
Hardware can be fun :)I'm not a hardware engineer.Me either. Drivers and firmware. :-)
This is true.
The buz works too. Currently The cards are aligend that way in my board:
bottom 32 bit PCI slot Ensoniq ES1371 (es1371)
2nd 32 bit PCI slot Zoran Corporation ZR36057PQC (buz)
3rd 32 bit PCI slot Brooktree Corporation Bt878 (bttv)
top 32 bit PCI slot Creative Labs SB Live! (emul10k1)
1st 64 bit PCI slot Adaptec AIC-7892A U160/m
2nd 64 bit PCI slot empty
AGP slot Matrox G550 AGP
Hmmm... This doesn't make much sense that it would work for you and not for me, in both cases.
Here's a couple thoughts:
1.) Have you changed the PCI defaults? (Bus mastering time, etc.) in the BIOS?
2.) Are you using ACPI?
