>Description:
I have a ZuluSCSI pico slim. It has the latest release firmware on it. It is connected to my Mac SE/30. WPA PSK auth, nothing fancy.
In MacOS 7.5.5 - OpenTransport seems to work fine.
In NetBSD 11.0_RC5 - the interface seems to work after a fresh boot - but after a short time (30 min ?) - it's dead. No dmesg errors, etc. Just no packets transferred (tcpdump is silent as well).
After this happened, the ZuluSCSI needed a cold start because warm rebooting into MacOS seems to have had the problem persisted. I did a power off and cold boot and was back online in MacOS.
I don't have any debug on the ZuluSCSI right now, and there are no errors or messages in zululog.txt.
Let me know if there is some other debug info I can get you.
>How-To-Repeat:
Connect ZS PS to Mac SE 30 with wifi configured. Configure rc.conf / dhcpcd etc to use dse0
