Thank you so much for helping with this. But I still have a problem: I get a NO DIALTONE error, even though there is clearly a dial tone. As for Samba, no, this is pretty much a clean installation of Ubuntu. -----Original Message----- From: Philippe Vouters [mailto:philippe.vouters@xxxxxxxxxxx] Sent: Monday, July 02, 2012 8:24 AM To: Andrew Merczynski-Hait Cc: Antonio Olivares; Marvin Stodolsky; Linmodems Subject: More information about your computer While efax is running on another terminal andrew@ubuntu-11:~$ sudo cat /proc/interrupts CPU0 0: 179 IO-APIC-edge timer 1: 254 IO-APIC-edge i8042 4: 16 IO-APIC-edge 6: 3 IO-APIC-edge floppy 7: 0 IO-APIC-edge parport0 8: 1 IO-APIC-edge rtc0 9: 0 IO-APIC-fasteoi acpi 14: 0 IO-APIC-edge ata_piix 15: 115572 IO-APIC-edge ata_piix 16: 9201 IO-APIC-fasteoi uhci_hcd:usb2, uhci_hcd:usb4, i915 17: 327 IO-APIC-fasteoi snd_ca0106, Intel ICH5 19: 0 IO-APIC-fasteoi uhci_hcd:usb3 20: 55078 IO-APIC-fasteoi eth0 21: 0 IO-APIC-fasteoi 537 23: 138528 IO-APIC-fasteoi ehci_hcd:usb1 NMI: 0 Non-maskable interrupts LOC: 1742086 Local timer interrupts SPU: 0 Spurious interrupts PMI: 0 Performance monitoring interrupts IWI: 0 IRQ work interrupts RES: 0 Rescheduling interrupts CAL: 0 Function call interrupts TLB: 0 TLB shootdowns TRM: 0 Thermal event interrupts THR: 0 Threshold APIC interrupts MCE: 0 Machine check exceptions MCP: 130 Machine check polls ERR: 0 MIS: 0 So no IRQ conflict for the 537 device. This also shows your processor is a single core. Your /var/log/syslog gets flooded with such kind of messages: Jan 5 14:40:39 ubuntu-11 kernel: [39585.162477] Inbound IN=eth0 OUT= MAC=00:11:11:ce:98:15:a4:ba:db:fb:8a:d1:08:00 SRC=10.10.5.100 DST=10.10.5.102 LEN=60 TOS=0x00 PREC=0x00 TTL=128 ID=11645 DF PROTO=TCP SPT=57892 DPT=445 WINDOW=8192 RES=0x00 SYN URGP=0 This adds work to the processor giving less time for wvdialconf and efax when they select with a timeout.
