Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
> Issue description: > root:~# lsb_release -a > No LSB modules are available. > Distributor ID: Ubuntu > Description: Ubuntu 22.04 LTS > Release: 22.04 > Codename: jammy > > root:~# uname -a > Linux dapu-Star-Lake 5.19.0-46-generic #47~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jun 21 15:35:31 UTC 2 x86_64 x86_64 x86_64 GNU/Linux > > root:~#nvme subsystem-reset /dev/nvme0 > > root:~#nvme list //This command will hang about 60 seconds. > > Issue analysis: > Maybe it hangs in function nvme_wait_reset. When we revert the following commit, this issue will disappear. > if (!nvme_wait_reset(ctrl)) > https://github.com/torvalds/linux/commit/1e866afd4bcdd01a70a5eddb4371158d3035ce03?diff=split
See Bugzilla for the full thread.
Anyway, I'm adding this regression to be tracked by regzbot:
#regzbot introduced: 1e866afd4bcdd0 https://bugzilla.kernel.org/show_bug.cgi?id=217745 #regzbot title: listing nvme devices hangs after subsystem reset
Thanks.
