I also have seen it occur on another PC (an older Dell 32 bit laptop, fwiw) using the same external drive setup, ie with four USB drives attached via a 7-in-1 D-Link USB hub. Two are 1TB ext4 drives, one is a 500GB ext4 drive, and the other drive was either a 1TB ext4 drive or a 500GB ntfs drive. I did try reproducing the freeze with just a single drive attached but wasn't successful, so perhaps the number of drives is relevant. Both PCs that I have seen the freeze on were running Ubuntu 10.10. To see the (truncated) debug log I suspended from a console using "/etc/init.d/sleep.sh force". The fact that FUSE was involved in comment #10 puzzles me, given that that bug dump starts off saying it's an EXT4-fs error on sdb1 - isn't ext4 purely a kernel driver? I assume FUSE would have been loaded because of the ntfs-3g driver loaded for sdf1? It's quite possible that comment #10 was a different bug entirely, because the system didn't freeze. If it is related, it might be relevant that the freezing problem also occurs with only external ext4 drives attached. FUSE might still have been loaded though at that time the PC used to have an internal ntfs partition. Does the reference to gnome-panel reading directory lblock 0 suggest gnome-panel was trying to read a configuration file? Those would all be on my ext4 home partition, which is on the internal drive. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
