Comment 1 Alan 2012-08-14 11:43:28 UTC
This looks like an I/O never completed but it may be a pointer to something else (eg sys_readahead/ext4 interaction). Assigning to the ext4 folk see if they have any thoughts but thats half guesswork 8)

Comment 3 Loris Luise 2012-08-24 10:05:12 UTC
I made 2 modifications on the server running linux and currently no more soft lockup has happened

1) removed irqbalance daemon from ubuntu server
2) unchecked "Synchronize guest time with host" from VM setting (VMWare esx)

Modification 1) most probably solved the problem.
Comment 4 Alain Brossard 2014-08-22 18:30:42 UTC
Hi,
  I had the same issue with Ubuntu 14.04 + Xen-4.4 and the same solution worked: remove irqbalance. Though I suspect it could be a question of lock timing and this problem could come back.
