charlie, thank you for reporting this bug and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. ** Summary changed: - system freezes after 30min of uptime + kernel BUG at /build/buildd/linux-2.6.35/fs/buffer.c:3346!; RIP: 0010:[<ffffffff8117bb8d>] [<ffffffff8117bb8d>] free_buffer_head+0x3d/0x50 ** Description changed: + WORKAROUND: After removing fglrx the system appears to be stable, I can + no longer reproduce the freeze. + here is the /var/syslog that appears right before the freeze Oct 10 22:19:55 Helios kernel: [ 9052.438463] lo: Disabled Privacy Extensions Oct 10 22:20:06 Helios kernel: [ 9063.416618] ------------[ cut here ]------------ Oct 10 22:20:06 Helios kernel: [ 9063.416623] kernel BUG at /build/buildd/linux-2.6.35/fs/buffer.c:3346!
