Bug 42227 – Unable to log in on (most) 2.6 kernels

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Guy Van Sanden 2004-02-20 01:07:49 UTC]

Reproducable (on the same system) with all 2.6.2 and 2.6.3 kernels (gentoo-dev-sources development-sources mm-sources).

The kernel seems to boot fine and the systems sits at the login prompt.
I can switch terminals and type ok, but I can not log in, neither as
root or as a user.
After entering the password the system just waits, and then says 'login
timed out'.

I can reach the system remotely, but I can't log in either, althoug the
connection is opened and stays open.
Below is the debug of an ssh session.

I only have these entries in the logs for the entire time that the
system was booted with 2.6.3:

-- end SSH session --

I ran memtest for a while and it reported no memory leaks, I'm guessing
this isn't hardware related.
Also, I can get into single user mode.


Reproducible: Always
Steps to Reproduce:
1. Compile any 2.6.2 or greater kernel
2. Reboot with that kernel
3. Try to log in

Actual Results:  
All logins time out

Expected Results:  
Log in correctly

Very similiar problem here. I've had problems with all kernels > 2.6.1, except it doesn't seem to start until I run xinit. After that, nothing will start, can't get a login prompt, etc. Let me know if you want a copy of my kernel config or emerge info. Don't know if it makes a difference, but this is on a Dell Inspiron 5150.

[Comment 2 Tim Yamin (RETIRED) 2004-02-21 11:05:28 UTC]

Try upgrading util-linux and pam?

[Comment 3 Guy Van Sanden 2004-02-22 04:29:29 UTC]

>Try upgrading util-linux and pam?

I have the latest (available) versions of both:
sys-libs/pam-0.77 
sys-apps/util-linux-2.12-r4 (r5 has an ebuild, but is masked)

[Comment 4 Tobias Gebhard 2004-02-24 00:21:01 UTC]

Same here.
Since I upgraded to kernel 2.6.3 I get this error.
The only thing I can do is a hard reset, because reboot also doesnt work.
But sometimes after a reboot i can login and work as usual.
2.4 works without problems.

[Comment 5 Michal Januszewski (RETIRED) 2004-03-28 02:07:55 UTC]

How about 2.6.4 and the latest 2.6.5_rc2? Is the problem still there with these versions?

[Comment 6 Guy Van Sanden 2004-03-28 03:16:36 UTC]

All kernels starting from the first 2.6.4 RC are fine.
I haven't tried 2.6.5 yet, but I expect that the problem remains resolved.

Thanks for your help.

[Comment 7 Michal Januszewski (RETIRED) 2004-03-28 05:39:53 UTC]

OK, I'm closing this since the problem seems to be solved by the newer kernel versions and since 2.6.4 is now marked stable. Feel free to reopen if it's not gone in 2.6.4.
