However, your computer seems to have another problem, generating too many interrupts. So I think that they cannot compare. > In fact the multiple serial card would never show up in the > proc/interrupts. That's something strange... > It is a PCI card thogh and of course uses an irq.

Probably dpti0 processes interrupts for too long. That's a know cause for getting "Too much work in interrupt" messages and loosing packets. You could try to dissociate dpti0 and eth0 from the same interrupt; check the BIOS if it allows association between PCI slot and IRQ line or move the card to another PCI slot. > 5: 2603035427 2603245593 IO-APIC-level eth1 That's certainly too much... > RX packets:126196 errors:0 dropped:0 overruns:0 frame:0 > TX packets:63016 errors:0 dropped:0 overruns:0 carrier:0 > RX bytes:12366600 (11.7 Mb) TX bytes:6164576 (5.8 Mb) ... for such low data volumes. > The blocks of 5 return at the same time , as the time differnce is > always 1sec off look pretty nasty Do you run by any chance eth3 with default 5 seconds comit interval ? I don't believe that the NICs or the driver are responsible for such behaviour. Most likely there's an APIC misbehaviour or something strange with the PCI bus. -- Bogdan Costescu IWR - Interdisziplinaeres Zentrum fuer Wissenschaftliches Rechnen Universitaet Heidelberg, INF 368, D-69120 Heidelberg, GERMANY Telephone: +49 6221 54 8869, Telefax: +49 6221 54 8868 E-mail: [email protected] _______________________________________________ vortex mailing list [email protected] http://www.scyld.com/mailman/listinfo/vortex
