Hi, since updating to stretch I have a weird issue with my Lenovo X201 laptop: Sometimes when waking up from suspend it "hangs". The symptoms are somewhat strange: - All open programs still work fine. - I can open a new tab inside of an existing terminal. The bash prompt appears just fine. - Any process I try to start hangs. - The CPU monitor in lxpanel shows 100% usage. I was not yet able to reliably reproduce the issue. I feel that it often happens after suspending on battery power. Has anyone ever experienced something similar? Any pointers as to where I should look for clues?
On the face of it, this sounds like an inaccessible file system. You can open new tabs and re-launch processes because (in the case of launching a new tab) the information is still in memory or (in the case of launching a new process using a previously-run program, such as bash), the file is available from the disk cache. You can't access new programs because that would involve pulling information from the disk, which you can't get to. That might be something to look into. Be aware that, if your disk is inaccessible, then logs might not be being written out either.
