Subject: [Bug 219367] New: mpt3sas constant warnings and card resets on aarch64 Cortex-A72: _get_st_from_smid+0x54/0x70
Date: Wed, 09 Oct 2024 06:24:32 +0000 [thread overview]
Message-ID: <bug-219367-11613@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=219367
Bug ID: 219367
Summary: mpt3sas constant warnings and card resets on aarch64
Cortex-A72: _get_st_from_smid+0x54/0x70
Product: SCSI Drivers
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: Other
Assignee: scsi_drivers-other@kernel-bugs.osdl.org
Reporter: me@ndoo.sg
Regression: No
After LSI 9300-8e is initialized, dmesg constantly outputs below error, and
card keeps timing out and resetting and re-probing drives, making it unusable.
WARNING: CPU: 3 PID: 0 at drivers/scsi/mpt3sas/mpt3sas_base.c:1532
_get_st_from_smid+0x54/0x70 [mpt3sas]
Observed on kernel versions:
6.10.0
6.10.11
6.10.12
Fedora 40 aarch64
Motherboard/SoC: SolidRun LX2160A CEx7 COM
Memory: 2x Micron 18ASF4G72HZ-3G2F1 (32GB each DDR4 3200MHz CL22 ECC SODIMM)
It may be an SoC/Cortex-A72 issue as there are several errata for memory/cache
issues on this ARM core.
However seeing as CA72 cores are relatively common in prosumer and hyperscale,
I'm seeking comment from mptXsas developers on whether any workaround is
possible.
Other notes: Am running OpenZFS that's in the midst of a resilver operation,
however the errors occasionally do appear even before the ZFS pool is imported.
Attached is the full bootlog and buffer.
