Hi, I have just checked this on v2.6.31-rc1 and v2.6.31-rc2-214-g34f2547 (I wanted to test this on v2.6.31-rc2 as well, but there I had other suspend-issues that are fixed in todays v2.6.31-rc2-214-g34f2547) For both v2.6.31-rc1 and v2.6.31-rc2-214-g34f2547 suspend to ram fails with the test procedure described below, but it works fine when I revert commit 5bb644a0fd25a5e083ecbfaa92a211db99aa6ef7 "mac80211: cancel/restart all timers across suspend/resume" Best regards, Jan Jan Scholz <scholz@xxxxxxxxxxxxxxxxxxxxx> writes: > Hi, > > I'm not sure if I experience the same bug on my apple iBook G4 (ppc > 7447A, altivec supported PowerBook6,5) or just something very similar. > > With v2.6.30-rc1 I noticed, that suspending to ram does not work if my > wireless card is 'up'.
