Asterisk & SMP: Is irqbalance Redundant on 2.6 Kernels?
Asterisk users, I posted the following email to the Fedora users list <https://www.redhat.com/archives/fedora-list/2006-March/msg04154.html> and it got no responses, so now I'm calling on your expertise. Please take a look at it and share your knowledge on the subject with me. Additionally, let me know if you believe what I am trying to do is critically flawed. It's possible

Compatibility Issues with dell poweredge 1950 and TE110P card
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,

Why is irqbalance not balancing?
I am running irqbalance with default configuration on an Atom 330 machine. This CPU has 2 physical cores + 2 SMT (aka Hyperthreading) cores. As shown below the interrupt for the eth0 device is always on CPUs 0 and 1, with CPUs 2 and 3 left idle. But why? Maybe irqbalance prefers physical cores? My understanding, though, is that the even-numbered CPUs are the physical cores, with the

irqbalance?
Hi All, If I turn off irqbalance xen/arch/x86/irq.c, does that actually stop XEN from balancing irqs across different physical cpus, or will that override the setting if there are too many interrupts and one of the cpus is overloaded. Example: i have 4 cpus and i have configured irqbalance= off, so there is no irqbalancing done by xen. Now if i have affintized all my physical interrutps to one

Performance problem on a linux bridge used for shaping.
Hello, Here is the situation. There is a machine with 3 intel gigabit card, 2 of them on PCI-X and in bridge, the 3rd is used only for management access. The machine is a dual Xeon 2.8GHz with HT. With 2.6.8 kernel from debian (testing) and htb with u32 on, i usually get about 30-40% software interrupts on CPU0 and CPU2, and without htb and u32, 10% less. Now, if I boot with 2.6.17.9 kernel,

Unexpected results using HTB qdisc
Hi All, I am using the script below to limit download rates and manage traffic for a certain IP address and testing the results using iperf. The rate that iperf reports is much higher than the rate I have configured for the HTB qdisc. It''s probably just some newbie trap that''s messing things up but I''m buggered if I can see it.

Fax and dial-up connection issues
I have a pretty large setup on one of my customers. Digium TE420B (with echo cancelling module), 3 Xorcom Astribanks with 32 FXS each and 1 Xorcom Astribank with 16 FXO. These FXO ports are NOT used for fax/data transmission, as they are connected to cell phones. Not really related to the issue, but there are also 250 SIP phones. The problem is that fax and dial-up connections are really

[PATCH 0 of 6 RESEND v2] blktap3/sring: shared ring between tapdisk and the front-end
This patch series introduces the shared ring used by the front-end to pass request descriptors to tapdisk, as well as responses from tapdisk to the front-end. Requests from this ring end up in tapdisk''s standard request queue. When the tapback daemon detects that the front-end tries to connect to the back-end, it spawns a tapdisk and tells it to connect to the shared ring. The shared
