In 3.4-rc7, if I suspend while bnep0 over btusb is connected, then resume, system dies with a backtrace. (Unfortunately, it is not exactly easy to capture). If I suspend without bnep0 active, resume works. (This has worked before, but "before" may mean 3.2 in this case). Can someone test/reproduce this? Ideas? Pavel PS: Under normal suspend/resume, I see these warnings in the log. Maybe relevant? ehci_hcd 0000:00:1d.7: GetStatus port:7 status 003002 0 ACK POWER OWNER sig=se0 CSC usb 5-2: finish reset-resume uhci_hcd 0000:00:1d.3: port 1 portsc 0093,00 usb 5-1: finish reset-resume usb 5-2: reset full-speed USB device number 3 using uhci_hcd usb 5-2: ep0 maxpacket = 8 usb 5-1: reset full-speed USB device number 2 using uhci_hcd btusb 5-1:1.0: no reset_resume for driver btusb? btusb 5-1:1.1: no reset_resume for driver btusb? btusb 5-1:1.0: forced unbind usb usb2: suspend_rh (auto-stop) usb usb3: suspend_rh (auto-stop) usb usb4: suspend_rh (auto-stop) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
