kdb, hm, i'll see if i can handle this. would some output from gdb help too?

the debugger will show, as nothing else showed up and even SysReq was
not working anymore.

last snippet of the "strace ifconfig eth1":

ioctl(4, 0x8916, 0x7ffffd78)            = -1 ENODEV (No such device)
dup(2)                                  = 5
fcntl64(5, F_GETFL)                     = 0x2 (flags O_RDWR)
fstat64(5, {st_mode=S_IFCHR|0600, st_rdev=makedev(5, 1), ...}) = 0
ioctl(5, TCGETS, {B38400 opost isig icanon echo ...}) = 0
= 0x30016000
_llseek(5, 0, 0x7ffffb68, SEEK_CUR)     = -1 ESPIPE (Illegal seek)
write(5, "SIOCSIFADDR: No such device\n", 28) = 28
close(5)                                = 0
munmap(0x30016000, 4096)                = 0
ioctl(4, 0x8913, 0x7ffffc98)            = -1 ENODEV (No such device)
write(2, "eth1: ERROR while getting interf"..., 58) = 58
exit(-1)                                = ?


BOFH excuse #231:

We had to turn off that service to comply with the CDA Bill.
