Subject: [REGRESSION][x86] Commit f5b2831d65 cause boot failure in VMware ESXi 5.1 guest
Date: Fri, 26 Dec 2014 09:57:42 +0800 [thread overview]
Message-ID: <549CC096.3080701@cn.fujitsu.com> (raw)
Hi all,
When testing v3.19-rc1 kernel(in fact, try to test), the kernel itself
fail to boot on VMware ESXi 5.1 guest.
The boot failure is quite easy to describe, only one line is output:
"Probing EDD (edd=off to disable)...ok"
No other output(including warning/bug_on/backtrace or whatever) and the
guest just hangs.
It's OK on v3.18, so it's a regression.
Bisect points to the following commit:
commit f5b2831d654167d77da8afbef4d2584897b12d0c

x86: Respect PAT bit when copying pte values between large and
normal pages
The PAT bit in the ptes is not moved to the correct position when
copying page protection attributes between entries of different sized
pages. Translate the ptes according to their page size.
I have also created the kernel BZ report:
https://bugzilla.kernel.org/show_bug.cgi?id=90321
Hopes this can be resolved in next rc.
Thanks,
Qu
