Re: [PATCH 4.4 00/37] 4.4.110-stable review

[Pavel Tatashin]

I tried cherry picking
 435086b36f62 x86/vsyscall/64: Explicitly set _PAGE_USER in the
pagetable hierarchy

on top of 4.4.110-rc1, (needed to resolve a small 5level table to
4level page table conflict). Unfortunately, this does not solve the
panic/hanging problem I reported. For some reason I do not see the
panic message anymore. Machine hangs here:

[    5.023052] zswap: loaded using pool lzo/zbud
[    5.023063] page_owner is disabled
[    5.026492] Key type trusted registered
[    5.029325] Key type encrypted registered
[    5.029330] ima: No TPM chip found, activating TPM-bypass!

[    5.216862] Freeing unused kernel memory: 1856K

And reboots after about half a minute.

Thank you,
