https://bugzilla.kernel.org/show_bug.cgi?id=217914 Bug ID: 217914 Summary: scsi_eh_1 process high cpu after upgrading to 6.5 Product: IO/Storage Version: 2.5 Hardware: All OS: Linux Status: NEW Severity: high Priority: P3 Component: SCSI Assignee: linux-scsi@xxxxxxxxxxxxxxx Reporter: laktak@xxxxxxxx Regression: Yes Bisected 624885209f31eb9985bf51abe204ecbffe2fdeea commit-id: Overview: Several users report that after upgrading from 6.4.12 to 6.5 the process scsi_eh_1 will constantly consume >10% CPU resources. This happens most often in VMs. Steps to Reproduce: - Create a VM (e.g. VMware Fusion) - Create an SCSI disk - Connect a virtual CD ROM (IDE) - Boot a 6.4.12 kernel - Boot a 6.5 kernel Actual Results: - no issues for the 6.4.12 kernel - scsi_eh consumes too much CPU with the 6.5 kernel Expected Results: scsi_eh should not consume significant resources. Build Date & Hardware: Linux arch 6.5.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Wed, 06 Sep 2023 21:01:01 +0000 x86_64 GNU/Linux inside a VMware Fusion VM Additional Builds and Platforms: Other users were able to reproduce the error on bare metal hardware.
