28 sky2: dont enable PME legacy mode
30 This bit is not changed by vendor driver, and should be left alone.
31 The documentation implies this a debug bit.
32 0 = WAKE# only asserted when VMAIN not available
33 1 = WAKE# is depend on wake events and independent of VMAIN.

66 Subject: [PATCH] xfs: start periodic workers later
67 Message-ID: <20110711135957.GA23737@infradead.org>
69 Content-Type: text/plain;
71 Content-Disposition: inline
72 User-Agent: Mutt/1.5.21 (2010-09-15)
74 Start the periodic sync workers only after we have finished xfs_mountfs
75 and thus fully set up the filesystem structures. Without this we can
76 call into xfs_qm_sync before the quotainfo strucute is set up if the
77 mount takes unusually long, and probably hit other incomplete states
80 Also clean up the xfs_fs_fill_super error path by using consistent
81 label names, and removing an impossible to reach case.

179 The RCU problem is likely to be a separate issue. It might even be a
180 result of the use-after-free problem with the elevator.
182 At any rate, it's clear that the crash in the refcounting log you
183 posted occurred because scsi_setup_blk_pc_cmnd() called
184 scsi_prep_state_check(), which tried to dereference the NULL pointer.
186 Would you like to try this patch to see if it fixes the problem? As I
187 said before, I'm not certain it's the best thing to do, but it worked

237 As reported by Ben Greer and Froncois Romieu. The code path in
238 the netif_carrier code leads it to try and disable
239 a late workqueue to reenable it immediately
241 -> linkwatch_fire_event
242 -> linkwatch_schedule_work
243 -> cancel_delayed_work
246 If __cancel_delayed_work is used instead then there is no
247 problem of waiting for running linkwatch_event.
249 There is a race between linkwatch_event running re-scheduling
250 but it is harmless to schedule an extra scan of the linkwatch queue.
