Re: [2.6.19-rc2-mm2] oops removing sd card

OK. After some testing I found something interesting: in vanilla
2.6.19-rc4 - tifm works (I mean "removing the SD card from the
FlashMedia controller does not oops")

So, as I'm pretty sure 2.6.18-mm3 didn't trigger the oops, the cause
is in something between 2.6.18-mm3 and 2.6.19-rc2-mm2.

However, the driver does not survive a suspend-to-disk cycle; I will
open another thread for this.

Regards,
Fabio

So put together some patches that will help you figure out the problem
via Fabio. Tracking an oops isn't usually that difficult (it's usually
some bogus pointer somewhere). Just sprinkle BUG_ON():s and printk:s all
over the place until you can pinpoint the offending pointer.
