Hi, I have just installed OpenBSD 5.5 on my ThinkPad T440. At first glance everything seems to work OK, except for the fact that, when shutting down or restarting, system hangs at 'hang at syncing disks... done'.
I need to hold power button in order to power it off. Disks are clean on next boot, no need for fsck. Any idea how to fix this? Thank you in advance. pacija@efreet:~ $ dmesg OpenBSD 5.5 (GENERIC.MP) #315: Wed Mar 5 09:37:46 MST 2014 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8246038528 (7864MB) avail mem = 8017915904 (7646MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xdcd3d000 (59 entries) bios0: vendor LENOVO version "GJET77WW (2.27 )" date 05/20/2014 bios0: LENOVO 20B6005RUS acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SLIC DBGP ECDT HPET APIC MCFG SSDT SSDT SSDT SSDT SSDT SSDT SSDT SSDT PCCT SSDT TCPA UEFI MSDM ASF!
