Is anyone running any Areca RAID controllers with the latest CentOS 7 kernel, 3.10.0-693.2.2.el7.x86_64? We recently updated (from 3.10.0-514.26.2.el7.x86_64), and we’ve started having lots of problems. To add to the confusion, there’s also a hardware problem (either with the controller or the backplane most likely) that we’re in the process of analyzing. Regardless, we have an ARC1883i, and with the older kernel the system is stable, but with the new kernel it locks up within 1-12 hours of boot, with errors in /var/log/messages that start with things like
kernel: arcmsr0: abort device command of scsi id = 0 lun = 0
(that is indeed the RAID scsi device) and within a few minutes of those also things like

Eventually the system locks up completely.
Has anyone seen anything like this with these controllers and the latest kernel, or have any ideas of what to look for?
thanks,
