https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264141 --- Comment #8 from crb <crb@ChrisBowman.com> --- Replacing nvme with nda results in similar looking messages from both nvme0= and nda0 (theses didn't show up in a remote ssh session so that I could cut and paste them). I don't think the cards get to hot. The machine has 3 fans that spin up wi= th cpu temperature and as I mentioned earlier the card has a heat sync. When I link while building world with 32 jobs I do hear the fans ramp ever so slig= htly but mostly they're quiet. I doubt it's cabling as these SSDs were directly inserted in to an M2 slot = and I seated the last one securely a few days ago. It could be power, this is a bit of a hacked system (I gutted a Sun Ultra 40 and replaced the contents with this reusing the power supply) but I don't h= ave a way to eliminate power as a possibility right now. Theoretically this sy= stem should be able to deliver 1000W and I only have the motherboard, processor,= 64 G memory, the SSD, 2 ethernet cards (one a Mellanox CX3 using fiber) and 6 spinning drives which are basically quiet. Power seems unlikely as the sys= tem seems otherwise rock solid with load except when hitting the SSD hard. This (unfortunately) seems to be completely repeatable now simple by copyin= g a couple of repo over 10G ether from a remote nfs machine to the local SSD wh= ile the machine is otherwise completely idle. --=20 You are receiving this mail because: You are the assignee for the bug.
