Some oddities from 2.5.67 to 2.5.70-mm3

[Edward Tandi (ed@efix.biz)]

I have been trying the 2.5.x series of kernels periodically. I have to
say it appears to be getting much better recently and it is nearly at
the point where I can use it to replace my 2.4 kernel. There are just a
few things that remain a problem for me.

I have included a brief report below. Any help with the 3 issues below
would be great.

Ed-T.


Configuration
-------------

Mandrake 9.1, Asus A7V8X (KT400), Athlon 1500XP, 1GB RAM, NVidia Ti4600,
Tulip based Network card.

Working: Network+NFS+ypbind, Audio, Gnome2, XMMS, mplayer, Browsers,
Evolution, UT2003, Half-Life under Winex3.0 and all apps under
CrossoverOffice. Almost everything works in fact.


Not working (3 items below)
---------------------------

1) gnome-terminal only works as user root
As a normal user, running '> gnome-terminal' brings up the window and
the command returns to the console without destroying the window. No
prompt appears in the window.

Output from strace:
socket(PF_UNIX, SOCK_STREAM, 0)         = 16
fcntl64(16, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
fcntl64(16, F_SETFD, FD_CLOEXEC)        = 0
connect(16, {sa_family=AF_UNIX,
path="/tmp/orbit-ed/linc-9be-0-37de7a363048"}, 39) = 0
writev(16, [{"GIOP\1\2\1\0\264\0\0\0", 12},
{"@\366\377\277\1\0\0\0\0\0\0\0\34\0\0\0\0\0\0\0I\350\250"..., 180}], 2)
= 192
writev(16, [{"GIOP\1\2\1\5\4\0\0\0", 12}, {"@\366\377\277", 4}], 2) = 16
close(16)                               = 0
write(10, "\1\v\1\0\1\0\0\0\0\0\0\0\0\0\0\0", 16) = 16
close(10)                               = 0
exit_group(0)                           = ?

As root I get the following warning from stdout/stderr:
(gnome-terminal:2860): GnomeUI-WARNING **: While connecting to session
manager:
Authentication Rejected, reason : None of the authentication protocols
specified are supported and host-based authentication failed.

2) xosview freezes
Window does not appear but command does not terminate.

3) Gamepad/rmmod issue

For some reason the system appears to be ignoring module parameters and
gets the type of my gamepad wrong. It may be because it is loading a new
module for which I don't have settings for in /etc/modules.conf. The
kernel appears to have two check-boxes for pc-joysticks. The biggest
problem is that I cannot remove the modules. '> rmmod analog' or any
other module for that matter gives:

Can't open 'analog': No such file or directory

rmmod _is_ supposed to be compatible with 2.5.x series kernels. From the
man page:
BACKWARDS COMPATIBILITY
 This version of rmmod is for kernels 2.5.48 and above.  If it detects a
 kernel with support for old-style modules (for which much of  the  work
 was  done in userspace), it will attempt to run rmmod.old in its place,
 so it is completely transparent to the user.

Also, "module unloading" is checked in the kernel build.


Other oddities
--------------

1) from /var/log/messages:
/sbin/mingetty[2583]: /dev/tty4: cannot open tty: Inappropriate ioctl
for device

2) Excessive anticipatory scheduler messages. from dmesg:
scsi2 : SCSI emulation for USB Mass Storage devices
anticipatory scheduling elevator
  Vendor: Datafab   Model: KECF-USB          Rev: 0113
    Type:   Direct-Access                      ANSI SCSI revision: 02

anticipatory scheduling elevator
Attached scsi removable disk sdb at scsi2, channel 0, id 0, lun 0

In fact it continues to be printed all over the place.

3) from dmesg:
process `named' is using obsolete setsockopt SO_BSDCOMPAT
process `named' is using obsolete setsockopt SO_BSDCOMPAT
process `named' is using obsolete setsockopt SO_BSDCOMPAT
process `named' is using obsolete setsockopt SO_BSDCOMPAT

process `named' is using obsolete setsockopt SO_BSDCOMPAT
named appears to be working however.
