Thanks for the report. To be sure the issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression
tracking bot:
#regzbot ^introduced v5.19..v6.0-rc7
#regzbot title nvme: system partially freezes with "nvme controller is down"
#regzbot ignore-activity
This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.
Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (the parent of this mail). See page linked in footer for
details.

For some reason the log [1] has very little of the kernel dmesg log.
It does seem like the freeze is partial (I see messages for hundreds
or thousands of seconds after the nvme reset), but requires a reboot
to recover.
The lspci information [2] shows the 00:1b.0 Root Port leading to the
01:00.0 NVMe device.
Is it possible to collect lspci output after the nvme freeze? If so,
please save the output of:
sudo lspci -vv -s00:1b.0
sudo lspci -vv -s01:00.0
Make sure to run lspci as root so we can see the error logging
registers for these devices.
If you can collect more of the dmesg log after the freeze, e.g., via
the "dmesg" command, that might be helpful, too.

Hi, this is your Linux kernel regression tracker. Top-posting for once,
to make this easily accessible to everyone.
I might be missing something, but it looks like this discussion stalled.
I wonder why.
Julian, did you ever share the data Bjorn asked for? Or tried a a
bisection, as suggested by Keith? Or did you stop caring for some
reason? Does everything maybe work fine these days?

Stop tracking this for now:
#regzbot inconclusive: stalled and might be a hw issue
#regzbot ignore-activity
