I've now done some testing with BIOS v3.0 and IPMI v1.92:
- 3 x shutdown with UPTIME < 10 min (PASS)
- 2 x shutdown with UPTIME = 15 min (FAIL)
- 1 x shutdown with UPTIME = 20 min (PASS)
- 1 x shutdown with UPTIME = 45 min (PASS)
- 1 x shutdown with UPTIME = 70 min (FAIL)
I recorded the shutdown sequence from the console via the iKVM and result is quite interesting - the shutdown sequence seems to be interrupted (refer to attachment).
My gut feel is that maybe fix for
Bug# 14537 is having an influence?
In the meantime, I'll report back to the Supermicro tech support.
