This has now been running fine for a year with no issues

ZFS, IBM M5110e and cross-flashing to IT mode I have a new to me IBM M4 that has a M5110e built into the main-board that I really wanted to use with TrueNAS/Proxmox. It looks like the accepted wisdom has been to just chuck in a flashed HBA, but I decided to do some digging. The blog post below is built on the good work of people at STH, serveian, the Art of Server and spikebytes.

This has only been flashed for 8 hours so no real testing has been done on it yet so use with caution
