Subject: [PATCH] arm64: tegra: Disable CQE Support for SDMMC4 on Tegra186
Date: Wed, 13 Feb 2019 13:17:29 +0000 [thread overview]
Message-ID: <1550063849-24719-1-git-send-email-jonathanh@nvidia.com> (raw)
From: Jonathan Hunter <jonathanh@nvidia.com>
Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression
that is causing accesses to the file-system on the eMMC to fail. Errors
such as the following have been observed ...
mmc2: running CQE recovery
mmc2: mmc_select_hs400 failed, error -110
print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700
mmc2: cqhci: CQE failed to exit halt state
For now disable CQE support for Tegra186 until this issue is resolved.
