Crashed with 0.5.16.

[Jamie Strandboge (jdstrand)]

Confirmed that it still crashes with usplash 0.5.16.

[Jamie Strandboge (jdstrand)]

I rebooted with the old -11 kernel and then again with the new -12 kernel, and this time no crash. I thought it might have had something to do with when I logged in, so I tried again and logged in as soon as gdm popped up, and still no crash. Seems the problem is intermittent.

[Jamie Strandboge (jdstrand)]

Just finished upgrading to latest hardy and rebooted and it crashed again.

[Savvas Radevic (medigeek)]

we know Jamie:
$ apt-cache policy usplash
  Installed: 0.5.16
  Candidate: 0.5.16

It's noted on the bug description, and we're awaiting a dev to take care of it :)

I've added a kernel task because this appears to be a problem somewhere between ioperm() and inb(). This is the only way that I know of that an "in" can segfault. In fact, I was able to reproduce the issue with the attached program. It would always segv. However, after a reboot, the behavior went away (same kernel). Something somewhere is very odd. :)

[Kees Cook (kees)]

This reproducer shows a SEGV for me after I start a kvm VM.

[jayp (jayp-free)]

apparently I have the same problem. I have the progress bar appear during the boot, but about 5 sec after the desktop appears, usplash just crash don't know why since I haven't started any other program manually yet at that time.

I think this is connected to bug 203299
I'm still facing that problem, usplash crashing on shutdown

Should I mark it as confirmed again?
