 Posted: Tue Jul 22, 2014 3:10 am Post subject: sdcard suddenly disappeared |
 |
|
Was working a short time ago; don't know what changed
but no longer recognizes cards or populates /dev
thinkpad T440S
lspci:
| Quote: | | 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01) |
when rtsx_pci module is inserted:
| Quote: | Jul 21 22:47:42 olwe kernel: rtsx_pci 0000:02:00.0: irq 63 for MSI/MSI-X
Jul 21 22:47:42 olwe kernel: rtsx_pci 0000:02:00.0: rtsx_pci_acquire_irq: pcr->msi_en = 1, pci->irq = 63
Jul 21 22:47:42 olwe kernel: rtsx_pci: probe of 0000:02:00.0 failed with error -110
|
kernel is 3.15.6 but earlier kernels show the same failure (that is, kernels where I know
the reader worked)
any help would be appreciated
EDIT: booted into windows; sdcard reader works fine

| Could be IOMMU related issue, try booting with intel_iommu=off kernel parameter. |

thanks for the tip, I tried the iommu thing but it made no difference
but the big news is that due to the hacking around of somebody over at
http://askubuntu.com/questions/492476/internal-sd-card-reader-not-mounted-detected-hp-realtek-rts5227
there is a modified driver taken from realtek's webpage (rts5227.ko)
this driver works after banging it into the /lib/modules...
** but after using this driver another reboot left me with no sd card reader found
in lspci !!! **
** then after a cold reboot, the original driver works again **
this sort of voodoo might suggest failing hardware

| It could also be that the computer's firmware entered some non-accepting state which was only fixed by a cold boot. |
