versatile: OOPS in apparmor

[Loïc Minier]

Hi

the arm versatile netboot images at http://ports.ubuntu.com/ubuntu-ports/dists/jaunty/main/installer-armel/current/images/versatile/netboot/

OOPS when using both kernel and initrd (didn't boot fully with only a kernel but didn't OOPS in early boot)

Note that this wasn't the final beta kernel, but I also tried with the final beta kernel, linux-image-2.6.28-11-versatile_2.6.28-11.37_armel.deb; this is the updated OOPS:

This has been fixed and will be in the next kernel upload.

Has this kernel update been done? I am getting the same basic issue on Jaunty Beta downloaded 2 days ago. To so not sure the issue is completely resolved.

[Loïc Minier (lool)]

This bug is a duplicate; make sure you comment on bug 344370. Yes, the update was done the 9th, and I just started the current images at http://ports.ubuntu.com/ubuntu-ports/dists/jaunty/main/installer-armel/current/images/versatile/netboot/ fine.
