Has anyone had any compatibility issues with a TE110P card installed on a Dell Poweredge 1950? I noted the following error on the LCD display of the Dell Poweredge 1950: E1711 PCI PErr Slot 1 E171F PCIE Fatal Error B0 D4 F0. The Dell hardware owners manual states that it means the system BIOS has reported a PCI parity error on a component that resides in PCI configuration space at bus 0,

...at this was (in their words) 'extremely low', with 'best' and > 'worst' readings of 99.975586% and 99.963379% respectively. Might want to give PCI latency setting a try, it helped for me. My ZTTEST would drop occasionally to 99.95% until I set: setpci -v -s 01:01.0 latency_timer=ff <--Digium PRI card setpci -v -s 01:04:0 latency_timer=ff <--Digium 401 4 X FXS setpci -v -s XX:XX:X latency_timer=0 <--1 entry for every other PCI card in system from LSPCI output, modify XX:XX accordingly Before setpci I would get best in ZTTEST at 99.987793% and worst ~ 99.95% A...

...nyone commment on long term effects with moderate load (say, 30 SIP phones / 2-3K calls /day) 3. Can anyone comment on using ramdisk as swap and whether this is a good idea or bad idea? I'm using 2.6 kernel. I've modified the PCI latency in rc.local: setpci -v -s <my T100P address> latency_timer=ff Anyone else have any performance tips?

I was browsing the applications developed in zaptel and came across zttest. After I run it, I get the following: Opened pseudo zap interface, measuring accuracy... 99.975586% 99.987793% 99.987793% 99.987793% 99.987793% 100.000000% 99.987793% 99.987793% 99.987793% 99.987793% 99.987793% 99.987793% 99.987793% 99.987793% 99.975586% 99.987793% 99.987793% 99.987793% 99.987793% 99.987793%

...ore IRQ choices). Run /usr/src/zaptel/zttest before and after and see if it makes any difference. If it does (i.e. ZTTEST yields ~98.X% before and ~99.X% after) then right there that's going to help. I have used these statements in /etc/rc.d/rc.local to good effect (YMMV) setpci -v -s 01:04:0 latency_timer=ff <--Specific statement for Digium TDM04, you will have to do lspci -vv for the pci vendor id of your specific Digium card setpci -v -s XX:XX:X latency_timer=0 <-- Replace XX:XX:X with the PCI Vendor ID of every other card that lspci -vv recognizes. What the setpci statements do is allo...

Guys. I have an issue with a te110p card and also some tdm04b cards on the same system: Zttest returns this for the tdm04b cards: [root@mollendo ~]# /usr/src/zaptel-1.2.4/zttest 38 -v Opened pseudo zap interface, measuring accuracy... 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.000000% 8192 samples in 8192 sample intervals 100.000000% 8192 samples

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
