Just to verify - your program was doing direct IO on block device with block size 512 bytes. Somehow the page user provided got freed before we got to it (that could possibly be a fault of Xen's tap:aio if it plays some dirty tricks ordinary userspace process couldn't do). So is tap:aio just an ordinary process using AIO/dio or does it do anything special? Regarding those EIO errors before - what filesystem do you use? There's a problem in ext3 which could cause EIO return from direct IO writes when they are combined with buffered writes. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
