I have got success compiling and loading ltmodem.o 5.78e & 5.95 from
http://www.heby.de/ltmodem on Mandrake 8.0, Mandrake 7.2. and Redhat 6.2.
But after dialing ISP (wvdial, kppp) after aprox. 10 sec of browsing
computer freezes.
I tried to lspci -vv, which reports IRQ sharing. I change my pci
cards in slots, so now modem does not share IRQ with other card, tried to
remove all unnecesary modules, disable onboard serial ports and usb
support, change VGA card, but freezing lasts anyway... I have feeling that
this happen when
browser is loading graphics(?) and on console in framebuffer mode (lynx)
everything works good. The same behaviour in win98, but removing other
cards or reinstalling windows helped.

cat /proc/interrupts, cat /proc/iomem, cat /proc/ioport reports seem ok -
no conflicts. I found no error messages in /var/log/messages

I am using VIA MVP3 motherboard with 3 PCI + 1 AGP slots: TV card with
BT787,
Sound Blaster 128 PCI, AGP VGA TNT2, Microcom interal/L modem, no ISA nor
PCMCIA cards, 196MB ram.

I post this on linmodems.org, but I think it is not problem of driver, but
hardware problem.

Any idea?

Martin
