Package: linux-image-6.1.0-9-armmp 6.1.27-1 I recently upgraded a Turris Omnia devce (https://docs.turris.cz/hw/omnia/omnia/) to debian bookworm. The newer kernel now produces a pair of repeated error messages a few times a minute: Jul 03 05:48:02 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0 Jul 03 05:48:02 kernel: pca953x 8-0071: failed reading register Jul 03 05:48:19 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0 Jul 03 05:48:19 host kernel: pca953x 8-0071: failed reading register Jul 03 05:48:57 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0 Jul 03 05:48:57 host kernel: pca953x 8-0071: failed reading register Jul 03 05:49:25 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0 Jul 03 05:49:25 host kernel: pca953x 8-0071: failed reading register This appears to be a regression, because the earlier kernel (5.10.0) did not produce these error messages. If there is any additional debugging information you'd find useful, i'm happy to try to gather it. These log messages are annoying because they mean additional writes to the logfiles. --dkg -- Package-specific info: ** Version: Linux version 6.1.0-9-armmp (debian-kernel@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP Debian 6.1.27-1 (2023-05-08) ** Command line: earlyprintk console=ttyS0,115200 root=/dev/mapper/host--vg-root cfg80211.freg=$regdomain pcie_aspm=off ** Not tainted ** Kernel log: Unable to read kernel log; any relevant messages should be attached ** Model information Hardware : Marvell Armada 380/385 (Device Tree) Revision nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables libcrc32c nfnetlink binfmt_misc sit tunnel4 ip_tunnel wireguard libchacha20poly1305 chacha_neon poly1305_arm ath9k curve25519_neon libcurve25519_generic ip6_udp_tunnel udp_tunnel ath9k_common ath9k_hw ath10k_pci ath10k_core x_tables autofs4 ext4 crc16 mbcache jbd2 crc32c_generic dm_crypt dm_mod gpio_pca953x mv88e6xxx dsa_core bridge stp llc selftests ehci_orion ehci_hcd ahci_mvebu i2c_mux_pca954x xhci_plat_hcd libahci_platform i2c_mux libahci xhci_hcd marvell libata mvmdio mvneta mdio_devres of_mdio fixed_phy phylink fwnode_mdio sdhci_pxav3 usbcore scsi_mod scsi_common sdhci_pltfm sdhci libphy spi_orion i2c_mv64xxx aes_arm_bs crypto_simd cryptd ** PCI devices: 00:01.0 PCI bridge [0604]: Marvell Technology Group Ltd. 88F6820 [Armada 385] ARM SoC [11ab:6820] (rev 04) (prog-if 00 [Normal decode]) Subsystem: Marvell Technology Group Ltd. 88F6820 [Armada 385] ARM SoC [11ab:11ab] Device tree node: /sys/firmware/devicetree/base/soc/pcie-controller/pcie@1,0 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+ Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Bus: primary=00, secondary=01, subordinate=01, sec-latency=0 I/O behind bridge: [disabled] [32-bit] Memory behind bridge: e0000000-e00fffff [size=1M] [32-bit] Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- <SERR- <PERR- BridgeCtl: Parity+ SERR+ NoISA- VGA- VGA16- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: <access denied> 00:02.0 PCI bridge [0604]: Marvell Technology Group Ltd. 88F6820 [Armada 385] ARM SoC [11ab:6820] (rev 04) (prog-if 00 [Normal decode]) Subsystem: Marvell Technology Group Ltd. 88F6820 [Armada 385] ARM SoC [11ab:11ab] Device tree node: /sys/firmware/devicetree/base/soc/pcie-controller/pcie@2,0 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+ Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Bus: primary=00, secondary=02, subordinate=02, sec-latency=0 I/O behind bridge: [disabled] [32-bit] Memory behind bridge: e0200000-e04fffff [size=3M] [32-bit] Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- <SERR- <PERR- BridgeCtl: Parity+ SERR+ NoISA- VGA- VGA16- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: <access denied> Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 002: ID 067b:2303 Prolific Technology, Inc.
