Here I have the same error, but we're using VMware. I tried to change de type os SCSI controller on VMware and the CentOS loaded other module too, but the VMs continues to displays this timeout erros on dmesg. The machine just do not respond to anything, and 3~5min after, it turns back to life.
I tried the MPT (mptscsih) and de VMware (vmw_pvscsi) module, in many kernel and CentOS version; all with the same error. I've also found this same error on old kernels like 2.6.18-308.4.1.el5.
Did you got this erros too? mptscsih: ioc0: task abort: SUCCESS (rv=2002) (sc=ffff8801378bdb80) mptscsih: ioc0: attempting task abort! (sc=ffff88013782b2c0)

Hi all,
I have updated my Centos 6.5 KVM host to kernel 2.6.32-431.23.3 this morning ... After 2 hours working, the following kernel error appears and all vm guests goes slowly ....
