Hello Tejun and Kay, I noticed problematic kernel messages when my laptop boots, bisecting this issue lead me to commit 523e1d399c. I attach the messages that I currently (commit e4e11180df) see, please let me know if further information is needed. The reason why I explicitely added Kay as a recipient is that I noticed these log messages when I bisected a problem with suspend to RAM on my laptop. Suspend works fine but not wakeup and I bisected this to commit 8a25a2fd12. I do not know if the kernel messages and the problem with wakeup are related but at least wanted to let Kay know this possible relationship of problems. Best regards, Dirk
