Hello,
since last kernel updates on ubuntu 20.04 and 22.04 we see lines like
this in syslog after boot:
Sep 7 13:10:53 myhost kernel: [ 1.202296] pci 0000:00:15.4: BAR 13: no
space for [io size 0x1000]
Sep 7 13:10:53 myhost kernel: [ 1.202387] pci 0000:00:15.4: BAR 13: failed
to assign [io size 0x1000]
We see this on Ubuntu 20.04 after installing kernel 5.4.0-162-generic and on
ubuntu 22.04 after installing kernel 5.15.0-83-generic
Since this time we notice some strange server behaviour.
- unexpected reboots during workhours
- systems hanging/freezing which requires a hardstop of the machine
- systems with high load but no significant number of processes, even on non
productive machines with usually zero load.
We use most of our ubuntu servers as virtual machines in a VMWare Environment
with VSphere and ESXi 7.0.3
There were no VMWare updates. I can say this with certainty because iam the
responsible person for VMWare too and i did not install any ESXi Updates last
days.
Other OS not affected as i can see.
Thank you,
Hans
p.s. i wanted to help and wanted to choose fitting package from dropdown "
In what package did you find this bug?" above this Inputfield, but it seems
that packages like linux-image-5.15.0-83-generic (or similiar i tried
somethging...) are unknown and search respondes with improper suggestions.
