[Kernel-packages] [Bug 1702998] Re: Ubuntu 17.04: Guest crashed @writeback_sb_inodes+0x310/0x590

2017-08-31 Thread Joseph Salisbury 
I built a Zesty test kernel with the requested two commits,
03e262798884b0a5f948b17433afd80606cb3497 and
f759741d9d913eb57784a94b9bca78b376fc26a9.  The also required a prereq
commit to built properly: b1d2dc5659b41741f5a29b2ade76ffb4e5bb13d8.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1702998/

Can you test this kernel and see if it resolves this bug?
