https://bugzilla.suse.com/show_bug.cgi?id=1219284 https://bugzilla.suse.com/show_bug.cgi?id=1219284#c11 --- Comment #11 from Michal Hocko <mhocko(a)suse.com> --- 6.6 AnonPages: 492536 kB AnonHugePages: 264192 kB 6.7 AnonPages: 770116 kB AnonHugePages: 399360 kB There is much more anonymous memory used in 6.7 kernel (~270MB). Daniel has already mentioned that this might be THP related but only part of it can be contributed to that (135MB). So some userspace had to consume more memory with the newer kernel which is rather unexpected. Are you sure you are comparing the exactly same userspace here? -- You are receiving this mail because: You are the assignee for the bug.

I attached the content of both measurement if you want to take a look. $ grep user_namespace slabinfo_6.* slabinfo_6.6.txt:user_namespace 13 13 624 13 2 : tunables 0 0 0 : slabdata 1 1 0 slabinfo_6.7.txt:user_namespace 25 25 632 25 4 : tunables 0 0 0 : slabdata 1 1 0 -- You are receiving this mail because: You are the assignee for the bug.

[Bug 1214049] USB audio dies after idle

https://bugzilla.suse.com/show_bug.cgi?id=1214049 https://bugzilla.suse.com/show_bug.cgi?id=1214049#c3 --- Comment #3 from Takashi Iwai <tiwai(a)suse.com> --- I guess it's rather a problem of the device (firmware) after the auto PM. Keeping the stream from pulseaudio prevents the device being runtime-suspended, hence you can work around it by that. Could you try to create the file /etc/modprobe.d/90-usb-audio.conf, including the following line, and retest? options snd-usb-audio quirk_flags=0x200 If you have more than one USB audio devices on the machine, pass the value at the right position (or just pass multiples like 0x200,0x200). -- You are receiving this mail because: You are the assignee for the bug.
