[Kernel-packages] [Bug 1831899] Re: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space
Is this easily reproducible? Can you retry with the latest released kernel 4.15.0-58.64? I haven't been able to reproduce the problem locally so far. It would help if you could share the container and workload, if that's possible at all. I'm still looking through the dumpfiles but haven't made much progress yet towards finding the root cause. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1831899 Title: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space Status in Ubuntu on IBM z Systems: In Progress Status in linux package in Ubuntu: New Status in linux source package in Bionic: New Bug description: == Comment: #0 - Robert J.

Hi Robert, yes I can access this file and have it already downloaded. It was just not clear to me that these are the same or similar dumps , so that the other (huge) files are not really needed... The tgz seems to be fine, since it's extractable w/o issues: $ tar xvfz 4_kdumps.tgz 201905311552/ 201905311552/dump.201905311552 201905311552/dmesg.201905311552 201906030926/ 201906030926/dmesg.201906030926 201906030926/dump.201906030926 201906041107/ 201906041107/dmesg.201906041107 201906041107/dump.201906041107 201906061158/ 201906061158/dmesg.201906061158 201906061158/dump.201906061158 kexec_cmd linux-image-4.15.0-50-generic-201905311552.crash linux-image-4.15.0-50-generic-201906030926.crash linux-image-4.15.0-50-generic-201906041107.crash -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1831899 Title: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space Status in Ubuntu on IBM z Systems: Triaged Status in linux package in Ubuntu: New Status in linux source package in Bionic: New Bug description: == Comment: #0 - Robert J.

[Kernel-packages] [Bug 1831899] Re: Kernel Oops 3b in libc-2.23 unable to handle pointer dereference in kernel virtual address space
Thx for the additional data.
However, I can confirm juergh that there is an issue with both dumps:
I downloaded them again from Box, but vmconvert is still not able to handle
them:
$ ls -l
total 5735304
-rw-rw-r-- 1 ubuntu ubuntu 2737907971 Aug 14 08:23 dump.190529.1324
-rw-rw-r-- 1 ubuntu ubuntu 3135030835 Aug 14 09:19 dump.190529.2120
$ vmconvert ./dump.190529.1324
vmconvert: Input file './dump.190529.1324' is not a vmdump
$ vmconvert ./dump.190529.2120
vmconvert: Input file './dump.190529.2120' is not a vmdump
$
Please can you try to vmconvert them on YOUR system?
And in case it works let us know which tool/version you used? ('vmconvert -v',
'apt-cache policy s390-tools', 'lsb_release -a' and 'uname -a')
Thx

I started to take a look at the dumps and noticed that there are faults in libc-2.17 (and not 2.23 as mentioned in the bug description). What are you running in those docker images?

Hi Robert, you may upload them to IBM box, I have an account there and may download them to the Canonical network - that's how I also do it with my IBM project mgr as well in case of dumps or other larger files. Thanks for sharing the additional information so far. But I'm still wondering about the libc version. The libc version in Bionic is 2.27, but I see 2.23 in the above strace which is the one from Xenial. rmadison --arch=s390x libc6 | egrep 'xenial|bionic' libc6 | 2.23-0ubuntu3 | xenial | s390x libc6 | 2.23-0ubuntu10 | xenial-security | s390x libc6 | 2.23-0ubuntu11 | xenial-updates | s390x libc6 | 2.27-3ubuntu1 | bionic | s390x On your system you should see the following output, pointing to 2.27: $ apt-cache policy libc6 libc6: Installed: 2.27-3ubuntu1 Candidate: 2.27-3ubuntu1 Version table: *** 2.27-3ubuntu1 500 500 http://us.ports.ubuntu.com/ubuntu-ports bionic/main s390x Packages 100 /var/lib/dpkg/status Please can you double check with 'apt-cache policy libc6'?

Hi does this happen on Ubuntu 18.04 or 16.04.5 ? (because kernel it's '4.15') lsb_release -a Since libc 2.23 is mentioned I assume it's 16.04.5. apt-cache policy libc6 linux-generic Please can you share a dump? As well as the 'dbginfo' output?
