FreeBSD ThinkpadT22.lan 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov  3 09:36:13 UTC 2005     root at x64.samsco.home:/usr/obj/usr/src/sys/GENERIC  i386
>Description:
The FreeBSD 6.0 release notes (http://www.freebsd.org/releases/6.0R/relnotes-i386.html) state "The snd_csa(4) driver now supports suspend and resume operation." However, on my Thinkpad T22, (with ACPI disabled), after a suspend/resume, sound no longer functions at all (until a reboot.) I have a Crystal Semiconductor 4280 sound chip. I had the same probem with Linux, but the problem could be gone around by reloading the module for my sound. kldunload snd_csa and kldload snd_csa don't work (it complains the device is busy.) Any possible workarounds would be welcome.
>How-To-Repeat:
Install FreeBSD 6.0 on a Thinkpad T22, load snd_csa, APM suspend/resume the laptop, note that sound no longer functions.
>Fix:
None.
