Hello, I'm experiencing a systematic crash in a fresh 5.5 install, starting the wsmoused service and then switch from console to X.
The following steps reliably reproduce the problem: 1) (from a X session) sudo wsconsctl display.focus=1 2) (from the wscons) sudo /etc/rc.d/wsmoused -f start 3) (from the wscons) sudo wsconsctl display.focus=4 (sometimes I need to switch back and forth between wscons and X to trigger the fault; as far as I can tell, it didn't happen on 5.4. This is the output of a ddb trace: kernel: page fault trap, code=0 Stopped at wsmux_do_close+0x35: cmpq %r12,0x98(%rbx) ddb{0}>trace wsmux_do_close() at wsmux_do_close+0x35 wsmuxclose() at wsmuxclose+0x42 spec_close() at spec_close+0x232 VOP_CLOSE() at VOP_CLOSE+0x2f vn_close() at vn_close+0x52 vn_closefile() at vn_closefile+0x6d fdrop() at fdrop+0x28 closef() at closef+0xab sysclose() at sys_close+0x52 syscall() at syscall+0x24f --- syscall (number 6) --- end of kernel end trace frame: 0x7f7ffffce700, count: -10 0x142785b0157a: ddb{0}> I found a thread initially describing a similar issue, but then focusing on a different kind of crash, which unfortunately doesn't help me at all: http://openbsd.7691.n7.nabble.com/Hard-Freeze-with-Snapshots-After-Aug-19-on-ThinkPad-X1-Carbon-td233555.html Tested with GENERIC.MP/amd64 on a Lenovo R61: just22@poseidon:[~]> uname -a OpenBSD poseidon.atlantide.net 5.5 GENERIC.MP#315 amd64 dmesg output follows: 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 = 2087387136 (1990MB) avail mem = 2023268352 (1929MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xe0010 (73 entries) bios0: vendor LENOVO version "7LETC1WW (2.21 )" date 07/01/2008 bios0: LENOVO 7735WX2 acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT ECDT TCPA APIC MCFG HPET BOOT ASF!
