Subject: [2.6.0-test-x] Kernel Oops and pppd segfault
Date: 04 Sep 2003 23:30:59 +0200 [thread overview]
Message-ID: <1062711059.8011.4.camel@mindfsck> (raw)
I have posted that to linux-ppp mailing list, but
no answer for 2 weeks now..
so here again:
I cannot get ppp working with 2.6.0-test kernels (test1, test3, test4)
I am using the ppp-2.4.1 package
Kernel config:
CONFIG_PPP=m
# CONFIG_PPP_MULTILINK is not set
# CONFIG_PPP_FILTER is not set
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
CONFIG_PPP_DEFLATE=m
CONFIG_PPP_BSDCOMP=m
# CONFIG_PPPOE is not set
and here comes the Oops when i want to start 'pppd':
PPP generic driver version 2.4.2
devfs_mk_cdev: could not append to parent for ppp
failed to register PPP device (-17)
Unable to handle kernel paging request at virtual address d1964580
printing eip:
