[Kernel-packages] [Bug 1867118] Re: dasd_fba io error and kernel panic
Patch landed in Ubuntu-5.4.0-55.61 (or newer) and since we are currently at:
linux-generic | 5.4.0.56.59 | focal-updates| s390x
the patch is included and rolled out (via -updates).
Hence updating focal entry to Fix Released.

[Kernel-packages] [Bug 1867118] Re: dasd_fba io error and kernel panic
Checking the focal git tree this is included in the Ubuntu kernels:
Ubuntu-5.4.0-55.61
Ubuntu-5.4.0-56.62
Ubuntu-5.4.0-57.63
And Ubuntu-5.4.0-56 just migrated to updates:
linux-generic | 5.4.0.56.59 | focal-updates| s390x
hence I'm updating this (focal) to Fix Released.

[Kernel-packages] [Bug 1867118] Re: dasd_fba io error and kernel panic
No, the issue is not yet fixed and rolled out with 20.04 updates.
It means that the issue is handled for focal/20.04 by the LP bug 1900624 and
that is just Fix Committed (and not yet Fix Released).
The status and plan is (as of today) that the commit 709192d531e5 ("s390/dasd:
Fix zero write for FBA devices") landed in Ubuntu's focal master-next git tree.
And according to 'kernel.ubuntu.com' an new binary kernel will be build and
made available for testing in '-proposed' around 13-Nov. And if the "Bug
verification & Regression testing" doesn't show any problems, this kernel will
then be released to '-updates' around 30-Nov.
All kernel updates are usually processed by 3-weekly 'kernel SRU' cycles that
are posted here: https://kernel.ubuntu.com/
But due to internal rearrangements and changes one SRU cycle is skipped this
time ("There will be no SRU cycle from October 12 through November 8.").
But the fix is already included in Ubuntu 20.10, which was released just
yesterday!
To shorten the time a bit until it get's released for focal/20.04, I
just compile a kernel based on the current master-next (that should have
the fix in) and made it available for testing here:

So it will find it's way into focal via this route.

[Kernel-packages] [Bug 1867118] Re: dasd_fba io error and kernel panic
Ican see that this patch was brought upstream on 20200923 and was picked up
with v5.9-rc7,
hence it's first of all not in stock 5.4 or 5.8.
Digging a bit deeper into this I found that it already landed in groovy
(Ubuntu-5.8.0-21.22) via:
"Groovy update: v5.8.13 upstream stable release"
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1898076
Hence it was obviously tagged upstream as stable update for the 5.8 series.
But I couldn't find it in current focal master-next.
So the questions is: was it also tagged as upstream stable update for the 5.4
series (which would be recommended)? Or does it need to be manually SRUed to
focal?

[Kernel-packages] [Bug 1867118] Re: dasd_fba io error and kernel panic
I tried to re-create the situation over here. I have a z/VM 6.4: q cplevel z/VM Version 6 Release 4.0, service level 1901 (64-bit) Generated at 06/14/19 14:15:49 UTC and there is a VM guest running from the time I did 18.04.4 regression testing, hence it's up since quite some time: buntu@zbox:~$ uptime 05:16:47 up 36 days, 22:17, 1 user, load average: 0.00, 0.00, 0.00 but has an older kernel: ubuntu@zbox:~$ lsb_release -a No LSB modules are available.

In other words I was not able to recreate the problem. I work on a z13 with a DS8870. What about your system?
