Hi,
I know that kernel 2.2.10 is a bit outdated, but one on ncpfs users
([EMAIL PROTECTED]) contacted me with strange problem. He is using
SuSE 6.2 with
Linux alpha 2.2.10 #8 Mon Nov 8 15:18:08 /etc/localtime 1999 i586 unknown
He is using Madge token ring card and when he tries to run ipx_interface,
machine oops on exit from ipx_interface program (IP traffic is OK):
execve("/usr/local/bin/ipx_interface", ["ipx_interface", "add", "-p", "tr0", "snap"],
[/* 45 vars */]) = 0
brk(0) = 0x804b1a8
[cut off loading binaries]
personality(PER_LINUX) = 0
getpid() = 1393
brk(0) = 0x804b1a8
brk(0x804b348) = 0x804b348
brk(0x804c000) = 0x804c000
socket(PF_IPX, SOCK_DGRAM, [PF_IPX]) = -1 ENOSYS (Function not implemented)
socket(PF_IPX, SOCK_DGRAM, [PF_IPX]) = -1 ENOSYS (Function not implemented)
socket(PF_IPX, SOCK_DGRAM, [PF_IPX]) = 3
ioctl(3, SIOCSIFADDR, 0x804b184) = 0
_exit(0) = ?
+++ killed by SIGSEGV +++
In syslog, following things appear (ok, I fix ipx_interface to close
socket before exit, but anyway...):

I have no clue what went wrong and before I recommend him to upgrade
to 2.2.14-pre12 (or what's latest), I'd like to know whether it will help,
as this does not happen with ethernet drivers...
Thanks,
