Hi, Alexey Will you please confirm whether the problem still exists if there is no cdrom in cddrive? Thanks. Created attachment 16505 [details]
dmesg no cdrom
Here is clean resume without cdrom
did a previous version of linux suspend correctly without this issue? if yes, what is the latest version that worked? I can't test regression due other supend bugs in older kernels. All i can say, it is present in 2.6.25 too, but i have more random crushes on resume. And at the moment is use SLUB kernel becouse it work better (not perfekt) with suspend/resume for me than SLAB. Seems like this is SLUB realted issue. I tested SLAB kernel and didn't get this message. Instead i get this one:
