i''d like to use my pcmcia UMTS card (Merlin U530) from Dom0 but it
doesn''t work. I''m using xen-unstable (kernel 2.6.12) on Fedora
Core 3
with the latest updates on an IBM Thinkpad T20 and I can connect to the
internet and ping servers, but I''m not able to reach a website with:
- firefox
- wget www.google.com
- telnet www.goolge. 80
I have disabled:
ipv6
iptables
acpi
in my kernel config, but still no success.
My grub configuration
-----------------------------
default=0
timeout=5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Fedora Core (2.6.12-1.1381_FC3)

Maybe somebody else uses a UMTS card ... what else can I try?

Is the driver for this card a generic driver supplied with the Linux distribution, or do you download the driver separately? There are some drivers that aren''t included in the OS that does things in "unconventional ways". Those drivers will not work in a Para-virtualized driver (including Xen Dom0). [And drivers that are included in the OS may still do things in unconventional ways and therefore need "fixing" to work with Xen, if these drivers aren''t commonly used in a Xen environment - maybe no-one has tried them in Xen before...] Do you see any error messages in dmesg or xm dmesg that may be of some help? -- Mats> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of > ralfsy@arcor.de > Sent: 18 November 2005 11:11 > To: xen-users@lists.xensource.com > Subject: [Xen-users] Problem with my UMTS card > > i''d like to use my pcmcia UMTS card (Merlin U530) from Dom0 > but it doesn''t work.

It just shows as a serial port device, and is controlled by special AT commands. Things you might want to check: - do you have pcmcia-drivers enabled in your dom0 Kernel? - do you see hotplug messages when you insert the card? - do you have a serial port driver in your kernel? - does the serial driver recognise the card? - since xen allocates a serial port for the console, the UMTS modem might end up on a different serial device (tts7 instead of tts8), check that, too /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The UMTS card seems to be a "simple" serial modem on /dev/ttyS3 that uses orinary modules: Module Size Used by ppp_deflate 4768 0 zlib_deflate 22520 1 ppp_deflate ppp_async 9536 1 crc_ccitt 1664 1 ppp_async ppp_generic 25716 6 ppp_deflate,ppp_async slhc 5920 1 ppp_generic serial_cs 8168 1 8250 34500 4 serial_cs serial_core 22560 1 8250 pcmcia 22824 9 serial_cs yenta_socket 20232 3 rsrc_nonstatic 11520 1 yenta_socket pcmcia_core 44068 4 serial_cs,pcmcia,yenta_socket, rsrc_nonstatic agpgart 30216 0 and it doesn''t share an interrupt with an other device: [root@tivoli ~]# cat /proc/interrupts CPU0 1: 91 Phys-irq i8042 11: 3770 Phys-irq CS46XX, yenta, yenta, serial 12: 896 Phys-irq i8042 14: 6136 Phys-irq ide0 15: 2268 Phys-irq ide1 256: 11863 Dynamic-irq timer0 257: 0 Dynamic-irq xenbus 258: 0 Dynamic-irq net-be-dbg NMI: 0 LOC: 0 ERR: 0 MIS: 0 I remeber, that I had a similar problem when I moved from kernel version 2.4 to 2.6 on redhat 9. I had to disable /proc/sys/net/ipv4/tcp_ecn to get a connection to the internet (icmp also worked, but no http possible). I have also tried other versions of Xen (stable | testing) and other kernel versions (2.6.11 | 2.6.12), but non of them works.
