Subject: Re: [2.6.19-rc2-mm2] oops removing sd card
Date: Mon, 23 Oct 2006 22:02:20 +0200 [thread overview]
Message-ID: <b637ec0b0610231302q700d0c79m65e73d16e21c06de@mail.gmail.com> (raw)
In-Reply-To: <b637ec0b0610220917l5b0720e6l76d349f91038e086@mail.gmail.com>
More info: I tried to use tifm_core.c and tifm_71xx.c from 2.6.18-mm3
with 2.6.19-rc2-mm2 and the crash also happens.
Hope this helps.
