Subject: [Bug 2048945] Re: scsi_eh_* process using idle CPU after upgrade to
kernel 6.5
Issue seems to have been fixed, with the bug report not being mentioned in the
changelog.
Tested on Ubuntu 22.04, with 6.5.0-28-generic, vSphere 6.5, ESXi 6.5, IDE
CD/DVD as Client Device.
I guess this can be closed.
@areis422 Can you test and confirm on your side as well?
