I've noticed that for 5.9, any VMs (in VMware) using vmx(4), end up putting "vmx0: device timeout" into the dmesg a bunch when under network load.
I switched one of the VMs to vic(4) and the messages stop. Another VM that I haven't gotten to upgrading from 5.8 to 5.9 yet doesn't show this in its dmesg and it's our reasonably busy web server. Anyone else see this? I noticed there were a bunch of changes to vmx(4) after 5.8 as part of the network mpsafe work. dmesg below. --Kurt OpenBSD 5.9 (GENERIC) #8: Thu Jul 14 20:12:37 CEST 2016 jas...@stable-59-amd64.mtier.org:/binpatchng/work-binpatch59-amd64/src/sys/arch/amd64/compile/GENERIC real mem = 1056899072 (1007MB) avail mem = 1020764160 (973MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xe0010 (364 entries) bios0: vendor Phoenix Technologies LTD version "6.00" date 09/17/2015 bios0: VMware, Inc.
