Public bug reported:
Binary package hint: linux-source-2.6.22
On an Everex StepNote 2053T laptop, loading the sdhci module causes the
machine to hang completely. SysRq keys don't work, and the only way to
reboot is to hold the power switch down.
This is a major problem, because the install disk and/or live CD tries
to load the module, so you can't install off a standard Ubuntu disk.The
only way to boot up is to blacklist this kernel, or buld a kernel
without the sdhci module.
This affects kernels 2.6.20 through 2.6.24; I haven't tested earlier
ones. I've found this problem on Ubuntu kernels from Feisty, Gutsy, and
Hoary Alpha 3 distributions, as well as straight kernel.org kernels that
I built from source (2.6.20, 2.6.22, 2.6.23, and 2.6.24 releases; didn't
technically test 2.6.21 but I imagine it's the same). There are no
obvious compile options for this module either, and no bootup options.
The card reader on this laptop is apparently an O2 Micro MMC, SD, Memory
Stick. Here's the lspci output that seems relevant:
03:06.2 Generic system peripheral [0805]: O2 Micro, Inc. Integrated
MMC/SD Controller [1217:7120] (rev 01)
03:06.3 Mass storage controller [0180]: O2 Micro, Inc. Integrated
MS/xD Controller [1217:7130] (rev 01)
If you need more info, or want someone to test solutions to this bug, be
sure to let me know. I'm comfortable applying patches, building
kernel.org source, running commands, etc.
The laptop testing page for this laptop (with more info about it) is
here: https://wiki.ubuntu.com/LaptopTestingTeam/EverexStepNoteSA2053T --
it is also affected by Bug #90271, which also makes it impossible to
boot (due to 8139too module issue).
