Description of problem: On a completely fresh install of FC2 Test 3 on a Toshiba A40 laptop (Celeron, 256MB), the first time that *any* user tries to log in to KDE, something (kdeinit?) hangs forever. This situation persists even after gdm is restarted, until the whole system is rebooted. Then, the user in question can log in OK, but other new users will experience the same problem. How reproducible: Sometimes The hang occurs when the login splash screen is showing the very last icon highlighted ("Restoring Session"). At this point, the system is still responsive; X is still up; the splash screen icon continues flashing and the mouse pointer works. I can switch to a terminal and kill gdm. However, interestingly, if I kill gdm and then try to log in again as the same user, the hang will occur again - but not necessarily at the same point in the login process (at least according to the flashing icons on the splash screen). The point at which it occurs seems to vary but in either case, the desktop never appears. If the system is rebooted, the user can then (and subsequently) log in without problems. This happened with the first (non-root) user that I created in the firstboot config, and exactly the same with a second subsequent user that I created later the same day, but with a third user that I've just tried creating (a couple of days later), everything worked OK. I have not applied any updates to the system. One thing which may or may not be related: on the *first ever boot* (*only*) after install, it does appear that kswapd and (immediately after) kdeinit segfaulted at the point of first ever login. I will attach the logs of the first boot including the kernel dump of the kdeinit crash. To summarise: 1. Create new user 'foo' 2. Login from gdm as 'foo' 3. First time: hang occurs whilst splash screen is on the last icon 4. Subsequent logins: hang occurs at random point 5. Reboot 6. Login now OK, both during current session and after subsequent reboots Possibly-related problem: - First ever login: kdeinit/kswapd segfault
Created attachment 99860 [details] Complete system log of first system boot/login showing kswapd/kdeinit segfault This log shows the complete first boot of the machine after installation. Key points: 15:08:30 - I (tim) log in for the first ever time. I've just created my local user account in the first boot configurator. 15:08:48 - kswapd segfaults followed by kdeinit 15:11:13 - I give up waiting for KDE to start (at this stage, the splash screen is showing but with "Restoring Session" endlessly flashing), and switch to a terminal where I log in as root 15:14:04 - I do "killall gdm" I must stress that although the "hang on login" problem occurred in exactly the same way when I subsequently added another local user, the segfaults of kswapd/kdeinit *have not occurred again*. The ONLY time they occurred is as shown in this attachment.
it looks like a kernel bug here.
It's probably worth noting that the same problem *did not* occur on a fresh install of FC2 final on the same machine.
reopen if it reoccurs.
