Looks like my system simply ran out of memory, and I didn't notice (because the page cache was still ~1 GB).
(Well, I did notice that it started using the disk more heavily, and blamed background cron jobs, and then two days later the system suddenly started thrashing so hard I had to reboot. When this happened again today, I noticed that all 3 gigs of swap were full, and that compiz ate 1.6 gigs of VM, and the system was thrashing despite the ~1 GB of page cache.) -- iwl3945: wireless stopped working after resume [jaunty] https://bugs.launchpad.net/bugs/364006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
