ata: pata_pxa: Fix DMA channel leak on probe error

2026-07-24T13:51:54+00:00

commit fcaf242e7fc406e78f444a35441e3b58f5e28781 upstream. When dmaengine_slave_config() fails, the DMA channel acquired by dma_request_chan() is not released before returning the error, leaking the channel reference. Fix by adding dma_release_channel() in the error path. The ata_host_activate() error path already correctly releases the DMA channel.

ata: sata_gemini: unwind clocks on IDE pinctrl errors

2026-07-24T13:51:43+00:00

[ Upstream commit c0ace4130e813acbabdfaa28d4e94a849c2ffdd7 ] gemini_sata_bridge_init() prepares and enables both SATA PCLKs, then disables them again while keeping the clocks prepared for later bridge start and stop operations. If gemini_setup_ide_pins() fails after that, gemini_sata_probe() returns directly and skips the existing out_unprep_clk unwind path. Route the IDE pinctrl failure through out_unprep_clk so the clocks prepared by gemini_sata_bridge_init() are unprepared before probe fails.

ata: ahci: force 32-bit DMA for JMicron JMB582/JMB585

2026-06-01T15:35:01+00:00

[ Upstream commit 105c42566a550e2d05fc14f763216a8765ee5d0e ] The JMicron JMB585 (and JMB582) SATA controllers advertise 64-bit DMA support via the S64A bit in the AHCI CAP register, but their 64-bit DMA implementation is defective. Under sustained I/O, DMA transfers targeting addresses above 4GB silently corrupt data -- writes land at incorrect memory addresses with no errors logged. The failure pattern is similar to the ASMedia ASM1061 (commit 20730e9b2778 ("ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers")), which also falsely advertised full 64-bit DMA support. However, the JMB585 requires a stricter 32-bit DMA mask rather than 43-bit, as corruption occurs with any address above 4GB. On the Minisforum N5 Pro specifically, the combination of the JMB585's broken 64-bit DMA with the AMD Family 1Ah (Strix Point) IOMMU causes silent data corruption that is only detectable via checksumming filesystems (BTRFS/ZFS scrub). The corruption occurs when 32-bit IOVA space is exhausted and the kernel transparently switches to 64-bit DMA addresses. Add device-specific PCI ID entries for the JMB582 (0x0582) and JMB585 (0x0585) before the generic JMicron class match, using a new board type that combines AHCI_HFLAG_IGN_IRQ_IF_ERR (preserving existing behavior) with AHCI_HFLAG_32BIT_ONLY to force 32-bit DMA masks.

ata: libata-scsi: Fix system suspend for a security locked drive

2025-12-06T21:09:33+00:00

[ Upstream commit b11890683380a36b8488229f818d5e76e8204587 ] Commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status handling") fixed ata_to_sense_error() to properly generate sense key ABORTED COMMAND (without any additional sense code), instead of the previous bogus sense key ILLEGAL REQUEST with the additional sense code UNALIGNED WRITE COMMAND, for a failed command. However, this broke suspend for Security locked drives (drives that have Security enabled, and have not been Security unlocked by boot firmware). The reason for this is that the SCSI disk driver, for the Synchronize Cache command only, treats any sense data with sense key ILLEGAL REQUEST as a successful command (regardless of ASC / ASCQ). After commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status handling") the code that treats any sense data with sense key ILLEGAL REQUEST as a successful command is no longer applicable, so the command fails, which causes the system suspend to be aborted: sd 1:0:0:0: PM: dpm_run_callback(): scsi_bus_suspend returns -5 sd 1:0:0:0: PM: failed to suspend async: error -5 PM: Some devices failed to suspend, or early wake event detected To make suspend work once again, for a Security locked device only, return sense data LOGICAL UNIT ACCESS NOT AUTHORIZED, the actual sense data which a real SCSI device would have returned if locked. The SCSI disk driver treats this sense data as a successful command.
