Bug#757733: 答复: Bug#757733: RTS2557 SD card reader does not work
Hi Wei,
I am affected by this bug too.
I patched the kernel source, recompiled the modules in drivers/mfd, and
it gives the following message when I run dmesg:
[ 3940.436153] rtsx_pci 0000:03:00.0: irq 50 for MSI/MSI-X
[ 3940.436185] rtsx_pci 0000:03:00.0: rtsx_pci_acquire_irq: pcr->msi_en
= 1, pci->irq = 50
[ 3940.535119] rtsx_pci 0000:03:00.0: rtsx_pci_init_hw error: optimize phy
[ 3940.535264] rtsx_pci: probe of 0000:03:00.0 failed with error -110
Cheers,
Fufu
