@Joseph "I noticed you upgraded to Oneiric on 2011-09-28. Were you having this issue before you upgraded?" I'm almost certain that I did a fresh install from a daily image instead of upgrading from Natty. I can't tell when the bug started to occur since I usually never disconnect the NTFS disk. If it is to any help, I could download and run a live CD of Natty and test?
"I believe you confirmed this only happens with NTFS?" When I excluded ext4 and fat32 I used a USB stick to do some quick testing. I now did some new tests with the same USB stick and I found that regardless of the file system used (tested ext2/3/4, fat, ntfs), the system didn't freeze when the stick was safely removed. Of course I should have taken the time to test the stick with NTFS from the start. Sorry for the confusion. I can therefore no longer say that it is NTFS only since I can only reproduce the freeze using my external hard drive (which I unfortunately cannot reformat and test with other file systems). I've tested with the upstream kernels that you gave me and I could not boot any kernels at all from 3.0.5 up to 3.1rc9. I never came past the plymouth screen. After booting into onerics kernel again, I received the paging request error from Apport mentioned above by Nicolás. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/867811 Title: Freeze when safely remove a NTFS disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/867811/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
