Can you tell us which snapshot was still working? > iwm0: unhandled firmware response 0xf2/0x12a84a5c rx ring 114[34] > iwm0: unhandled firmware response 0xff/0x80 rx ring 127[255] > iwm0: unhandled firmware response 0xb7/0x154a7 rx ring 0[0] > iwm0: unhandled firmware response 0x15/0x12a9af7f rx ring 114[35] > iwm0: unhandled firmware response 0xff/0x4208 rx ring 127[255] > iwm0: unhandled firmware response 0xf3/0x12a9da5d rx ring 114[35] > iwm0: unhandled firmware response 0xff/0x80 rx ring 127[255] > iwm0: unhandled firmware response 0xb7/0x154ae rx ring 0[0] > iwm0: unhandled firmware response 0x57/0x12ab54c1 rx ring 114[37] > iwm0: unhandled firmware response 0x18/0x264288 rx ring 46[15] > iwm0: unhandled firmware response 0xf1/0x12ab6a5b rx ring 114[37] > iwm0: unhandled firmware response 0xff/0x80 rx ring 127[255] > iwm0: unhandled firmware response 0xbd/0x154bf rx ring 0[0] > iwm0: unhandled firmware response 0xf1/0x12acfa5b rx ring 114[38] > iwm0: unhandled firmware response 0xff/0x80 rx ring 127[255] > iwm0: unhandled firmware response 0xbe/0x154d2 rx ring 0[0] > iwm0: unhandled firmware response 0xee/0x10 rx ring 0[3] > iwm0: could not load firmware > iwm0: failed to load init firmware > iwm0: unhandled firmware response 0xee/0x10 rx ring 0[3] > iwm0: could not load firmware > iwm0: failed to load init firmware > > When trying to re-associate I get this: > > $ doas sh /etc/netstart iwm0 > ifconfig: SIOCS80211NWID: Resource temporarily unavailable > interface_link_forceup: SIOCSIFFLAGS UP failed (Resource temporarily > unavailable) > iwm0: no link ........... sleeping > > I've only managed to make iwm work again by rebooting. > > $ pkg_info | grep iwm > iwm-firmware-0.20160412 firmware binary images for iwm(4) driver > > $ ifconfig iwm0 > iwm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 > lladdr 18:5e:0f:ae:37:15 > index 2 priority 4 llprio 3 > groups: wlan egress > media: IEEE802.11 autoselect (HT-MCS3 mode 11n) > status: active > ieee80211: nwid CYTA52E3 chan 11 bssid f8:df:a8:df:52:e3 88% > wpakey <not displayed> wpaprotos wpa2 wpaakms psk wpaciphers ccmp > wpagroupcipher ccmp > inet 192.168.1.5 netmask 0xffffff00 broadcast 192.168.1.255 > > $ dmesg > OpenBSD 6.0-current (GENERIC.MP) #1: Sun Jan 22 19:06:10 GMT 2017 > [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP > real mem = 8277159936 (7893MB) > avail mem = 8021659648 (7650MB) > mpath0 at root > scsibus0 at mpath0: 256 targets > mainbus0 at root > bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xacbfd000 (64 entries) > bios0: vendor LENOVO version "N10ET46W (1.25 )" date 11/28/2016 > bios0: LENOVO 20CM0027UK > acpi0 at bios0: rev 2 > acpi0: sleep states S0 S3 S4 S5 > acpi0: tables DSDT FACP SLIC ASF!
