I have added your ppa but when I run `sudo apt update sudo apt

The Kernel installed in our environment is compiled using GCC 4.8.2
(check dmesg | head). Hence I don't think this is related.
We had the kernel panic again last week (see attachment). We added the
hpwdt module to blacklist, which hopefully works around this problem. We
also updated the BIOS, but
lvm, the next step is to fully reverse commit bisect in order to
identify the fix commit. Could you please do this following
