Hello, I have investigated the issue a bit further, I was not able to find the root cause, maybe it is the KT133 Chipset of my ASUS A7V. However I found a bad hack to make it work under some circumstances. I commented out the line:
printk(KERN_CRIT "zaphfc: sync lost, pci performance too low. you might have some cpu throtteling enabled.\n"); in zaphfc/zaphfc.c. Since when this situation happened once, the syslog started and this caused the situation again -> endless loop with high sysload. Now the sync lost happens probably every now and then but it does not go into an endless loop. I also recognized that I must not run setiathome since then the audio quality of connections via the hfc-card will suffer (crackling). Amazingly cpuburn (takes every cpu-Time it gets as well) does not have this effect. I have no idea what strange things setiathome does to cause this but it reminds me of a sound card problem on this board. My SB-Live had crackling when I ran setiathome but I think with a newer driver (and ALSA I think) this problem was gone. Things that did not help: - Trying to change the latency (is fixed to 16 and cannot be changed) - Trying to change the latency of my other pci-devices (much higher and much lower). - Playing around with BIOS Options like delayed transaction, etc. - Changing PCI-slots - Making sure that the ISDN-card did not share the IRQ - Having only the ISDN-card and the Video-card in the System Hope that helps others who encounter this problem as well Hartmut On Sat, Sep 11, 2004 at 12:55:21PM +0200, Hartmut Wahl wrote: > Hi! > > On Sat, Sep 11, 2004 at 10:38:48AM +0200, Maurizio Marini wrote: > > my machine did hangup as growing logs fullfilled partition > > hmm I see, mine is 8G, but it has gronwn from 0.5G to 2.0G > > > it does apply to asterisk, not to zaphfc :( > > it was a misleading suggestion, so > > i solved it installing in an other more powerful machine: > > > > processor : 0 > > vendor_id : GenuineIntel > > cpu family : 6 > > model : 8 > > model name : Pentium III (Coppermine) > > stepping : 10 > > cpu MHz : 999.556 > > cache size : 256 KB > > fdiv_bug : no > > hlt_bug : no > > f00f_bug : no > > coma_bug : no > > fpu : yes > > fpu_exception : yes > > cpuid level : 2 > > wp : yes > > flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca > > cmov pat pse36 mmx fxsr sse > > bogomips : 1957.88 > > > > with this hw i've no issues at all; even strange messages i complained about > > in my previous posts like: > > ok we are getting closer, although speed shouldn't be a problem: > > vendor_id : AuthenticAMD > model name : AMD Athlon(tm) Processor > stepping : 4 > cpu MHz : 1059.618 > cache size : 256 KB > bogomips : 2097.15 > > it is a 1,4GHz underclocked, since my ASUS A7V with KT133 does only > support 100MHz FSB, but it requires only slow and quite fans. > > I think I'll try different kernels maybe something in the Debian > k7-kernel-image interferes. > > Greetings > Hartmut > -- Hartmut Wahl <hwahl (at) hwahl (dot) de> www: http://www.hwahl.de PGP: http://www.hwahl.de/HartmutWahl.asc _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
