Ok I found the responsible even if it's not the solution. I copy here
the bug report for speedtouch package since I don't know if it is a
kernel bug or a speedtouch bug. Nevertheless, it makes me stay with
2.6.5...
Hi,
Since linux 2.6.6 (not present in 2.6.5), modem_run makes ohci-hcd oops
when rmmoded. The oops is completely repeatable and completely
dependant of modem_run. It appears in the following conditions :
I boot in 2.6.6-powerpc with the following modules
usbhid 31264 0
n_hdlc 10888 1
ohci_hcd 24260 0
usbcore 125144 5 usb_storage,usbhid,ohci_hcd
Not the speedtouch kernel module.
I launch modem_run -s -f mgmt.o. This gives the syslog output :
modem_run[752]: [monitoring report] ADSL link went up
modem_run[747]: ADSL synchronization has been obtained
modem_run[747]: ADSL line is up (640 kbit/s down | 160 kbit/s up)
modem_run[752]: Error reading interrupts
modem_run[752]: [monitoring report] ADSL link went down
modem_run[752]: Device disconnected, shutting down
modem_run[747]: pusb_release_interface 2 failed
Output is the same with the speedtouch kernel driver.
I then start and stop pppd.
Then when I rmmod ohci_hcd (too put my ibook to sleep) or when I unplug
the modem, I got the following oops :
ohci_hcd 0001:01:18.0: remove, state 1
usb usb1: USB disconnect, address 1
usb 1-1: USB disconnect, address 2
Oops: kernel access of bad area, sig: 11 [#1]

I don't know if it is kernel related, but it only appears with my
speedtouch modem.
