Aren't apic and acpi different things? ------------------------------ That is fantastic... THanks. I did not realize two differnt things.

how to correctly turn off apic at boot
by Jerry Geis 19 Dec '05

19 Dec '05

I have tried in the grub.conf file noapic and apic=off I am still getting the same error message about ACPI in the dmesg output. example: ACPI: PCI interupt .... IRQ 16 eth0: RealTek RTL8139 ... IRQ16 eth0: identified 8139 chip type so ACPI is grabbing IRQ 16 and not letting eth0 have it. (I Think). How do I correctly disable it on my compaq v2000 laptop. I think it is not allowing my usb and realtek network to function. Jerry

Hmmm, I've gotta apologize, I just haven't messed with enough Intel chipsets in a long, long time. I've switched away from the legacy GTL+ non-sense to AMD's completely virtualized bus over EV6/HyperTransport and haven't seen an IRQ issue ... _ever_. ---------------------- I've not had interrupt conflicts since I left ISA!!!! What do I do now??? I tried adding noapic to the grub.conf line had no effect... I tried looking in the bios - nothing... THanks, Jerry

What is the exact model of your USB storage device? What does "lsusb" give you, if anything? What about what comes up in /var/log/messages when you stick the device in? [ tail -f /var/log/messages, then stick in the device ] ------------------ sticking the device in gives nothing further in /var/log/messages. lsmod | grep hcd shows the 3rd column as "0" as not in use... lsusb gives no output. I am just using a lexar usb device jumpdrive. There is no other writing on it other than 128M. (Has worked in everything else I've stuck it in). Interesting thing is lookin at dmesg says lines like: ehci_hcd requesing interrupt 23 failed ACPI -> GSI IRQ 23 uhci_hcd requesting interrupt 19 failed ACPI -> GSI 19 IRQ 19 Jerry

Sorry man, just tossed the cookies there, that statement was just too funny. [ Insider knowledge: USB was never designed for block devices ] Anyhoo, understand that USB isn't a set of standards, never was. Although some standards have been built around it for various functionality. Furthermore, you still have to have an OHCI (1.2/12Mbps) or EHCI (480Mbps) driver for your host. End user devices are up in the air, although most storage devices have come up with simple block mechanisms that are typically followed. >/ I thought trying to recompile the kernel for realtek />/ support might get my networking going... />/ I am stuck??? / Depends on your chipset.

Setting up a simple NAT on CentOS 3.5
by Robert Moskowitz 19 Dec '05

19 Dec '05

Well I think this system is back on 3.5. How do I tell? Have not used it in a while... I need a NAT for some quick testing and this box was available. Only a 6gb drive, so I can't install Astaro (which I have licenses for). So is there a simple way to turn on NATing? Should I upgrade to 4.2? This box is behind a firewall, so security risks are not the issue. This time.

Where is the kernel source code???
by lnthai2002＠aim.com 19 Dec '05

19 Dec '05

I have centOS 4 installed on my machine but some how it does not support my TV capture card (bt878) in the kernel, so i want to recompile the kernel to add support for my device. However, i cant find centOS 4 kernel source code. I have read some messages in the mailing list and someone said that i just need to yum install kernel-sourcecode to get the source code, i did it but i yum reported that there is no package matched.

To continue here with problems on this compaq v2000 laptop, I put kernel source on a USB disk and plugged it into the v2000. NOTHING IS recognized. I tried to manually mount the disk and nothing either... I thought USB was well established.... I thought trying to recompile the kernel for realtek support might get my networking going... I am stuck??? Jerry

It's not supposed to start in runlevel 3. It's only supposed to run in levels 4 and 5. > The init process only runs K* under runlevel 4 (rc4.d) when exiting > runlevel 4, then runs all of the S* stuff under the new runlevel. > $0.02, no more, no less .... That's not what the rc script appears to be doing. It simply checks the current runlevel and then runs all the scripts in that directory (kill scripts first, and then start scripts). -- Bowie

I have a system that is running into problems with high load, however, even when I shut down everything that could be loading the system, the load continues to rise. I can't see anything that is causing the load. Any ideas? 08:36:06 up 1 day, 10:57, 3 users, load average: 19.98, 19.30, 17.29 90 processes: 75 sleeping, 2 running, 13 zombie, 0 stopped CPU states: cpu user nice system irq softirq iowait idle total 0.1% 0.0% 0.0% 0.1% 0.0% 0.0% 99.6% Mem: 511916k av, 317756k used, 194160k free, 0k shrd, 35040k buff 208896k actv, 67280k in_d, 10488k in_c Swap: 2048276k av, 5872k used, 2042404k free 172064k cached -- Chris Mason
