julian 2007-11-14 05:43:55 UTC FreeBSD src repository Modified files: sys/i386/bios apm.c Log: Apply the same sort of locking done in sys/dev/acpica/acpi.c rev 1.196 a while ago: Grab Giant around calls to DEVICE_SUSPEND/RESUME in acpi_SetSleepState(). If we are resuming non-MPSAFE drivers, they need Giant held for them. This may fix some obscure suspend/resume problems. It has fixed keyrate setting problems that were triggered by cardbus (MPSAFE) changing the ordering for syscons resume (non-MPSAFE). Also, add some asserts that Giant is held in our suspend/resume and shutdown methods. Submitted by: Marko Zec Revision Changes Path 1.149 +10 -0 src/sys/i386/bios/apm.c
