modprobe: Error inserting ppp_mppe

[Fredrik Wendt <fredrik@…>]

I've failed to get GPRS working with M3 testing.

1. Started off by downloading the following files from downloads.free...:

   root@t61-laptopt:/opt/openmoko/dfu-util/FSO/testing# ls -1
   modules-2.6.24+r7+gitrca19d156400f817960efe0d14680324b2ea34171-r7-om-gta02.tgz
   openmoko-fso-image-glibc-ipk--20080919-om-gta02.rootfs.jffs2.summary
   uImage-2.6.24+r7+gitrca19d156400f817960efe0d14680324b2ea34171-r7-om-gta02.bin
   

2. Used dfu-util to first push uImage* followed by *rootfs*.
3. After the push was completed, I chose reboot in the menu on the phone.
4. The device booted as it normally does.
5. When X had started (ying-yang symbol gone) I manually started zhone (since it didn't (isn't supposed to?) start on it's own).
6. The phone registered to the network (I saw the network name).
7. Tried to connect via GPRS using the attached gprs-on.py. Tells me that the network is down.
8. Run "mdbus -s org.freesmartphone.ophoned /org/freesmartphone/GSM/Device org.freesmartphone.GSM.Network.Register" to make it register again. It does and is up again in two seconds or less.
9. Run the same gprs-on.py script again.
10. Start looking at the log using logread. Nothing happens but I notice a couple of

daemon.notice modprobe: FATAL: Error inserting ppp_mppe (/lib/modules/2.6.24/kernel/drivers/net/ppp_mppe.ko): No such device messages.

11. I look at the ppp_mppe.ko file and notice that it's smaller than that in the modules*.tgz file downloaded in step 1, so I gave that file a try:

    root@om-gta02:/media/card/away/root# ls -la /lib/modules/2.6.24/kernel/drivers/net/ppp_mppe.ko
    -rw-r--r--    1 root     root         9108 Jan  1  1970 /lib/modules/2.6.24/kernel/drivers/net/ppp_mppe.ko
    root@om-gta02:/media/card/away/root# mv ppp_mppe.ko /lib/modules/2.6.24/kernel/drivers/net/
    root@om-gta02:/media/card/away/root# ls -la /lib/modules/2.6.24/kernel/drivers/net/ppp_mppe.ko
    -rw-r--r--    1 root     root       116676 Sep 18 18:02 /lib/modules/2.6.24/kernel/drivers/net/ppp_mppe.ko
    

but to no avail.

I've used the exact same SIM and gprs-on.py script before succesfully. I'll double check now with a FSO M2 release that is known to work for me.

[Fredrik Wendt <fredrik@…>]

Just wanted to confirm that I got it working with the old M2 release.

N.B.: This is just a proof that it does work with the M2 release (same settings / same script)

[Fredrik Wendt <fredrik@…>]

I just tried with the official M3 release from downloads.openmoko.org and that release has the same issues with the missing module. Basically, you can't use GPRS on *any* M3 release up till today (I actually tried all on freesmartphone.org in order to find something that can let me read my RSS feeds on way to work).

The ppp_mppe is no problem, you can safely ignore that. The thing that changed for MS3 is that we now honor the user and password you give in ActivateContext?. We default to using CHAP, perhaps your provider only works with PAP. Is your provider actually requiring a user and a password? Most do not, please try without.

[Fredrik Wendt <fredrik@…>]

Been working too much lately - it works perfectly if I set username and password to an empty string (which was pointed out in another ticket as well). Sorry for the buz.
