2.6.11-rc3: oops in pdflush
Hi, rc3 vanilla oopses within 2 or 3 hours of heavy io load (rdiff-backup of ide disk (reiserfs3) to usb-storage (reiserfs3 on dm-crypt) and listening to internet radio in parallel). This is 100% reproducable here. Usually there occur 4 or 5 of very similar looking oopses within 3 hours until the machine is not usable anymore (all commands stuck, sysrq-sync not completing) and I have to reboot. To me the error message looks like a lock imbalance but I'm not a kernel hacker... Does anybody have an idea whats going on here? Please CC me as I'm not subscribed. Thank you.
