Reverting > this patch fixes the problem. The problem exists in 0.9.5 through 1.0.2c. Just FYI: a similar problem was introduced in intel8x0, also around that time. Note: the uninterruptible sleep issue only applies to the software using native ALSA, OSS emulation users seem to survive the suspend. Best regards, -- Karol 'sziwan' Kozimor sziwan@hell.org.pl
