Bug#594684: xserver-xorg-video-siliconmotion: siliconmotion driver segfaults on a Lemote YeeLoong (SM712 LynxEM+)
Package: xserver-xorg-video-siliconmotion
Version: 1:1.7.4-1
Severity: important
*** Please type your report below this line ***
I use a Yemote YeeLoong MIPS-based netbook:
http://wiki.gnewsense.org/Projects/Lemote#toc17
I use the extra staging (kernel) driver sm7xx to be able to use the console
at all (See http://bugs.debian.org/594642 ).
If I have xserver-xorg-video-siliconmotion installed on my system (either
the one from testing or the one from experimental), X crashes at startup.
I have to remove it. This allows the fbdev video driver to be used (which
works generally well).
I was not able to get any useful backtrace from the core file. So I added
some debug messages to the driver. The last part of the log below with
those debug messages (befault the segfault message):
(II) SMI(0): No legacy BIOS found -- trying PCI
(EE) SMI(0): Cannot read V_BIOS (5) No such file or directory
(WW) SMI(0): VBE initialization failed: falling back to UseBIOS disabled.
(--) SMI(0): Chipset: "LynxEM+"
(==) SMI(0): Dual head disabled
(==) SMI(0): Using XAA acceleration architecture
(==) SMI(0): Tzafrir: Msg1 (SMI_PreInit)
(==) SMI(0): Tzafrir: Msg2 (SMI_PreInit)
(==) SMI(0): Tzafrir: Starting (SMI_MapMmio)
(==) SMI(0): Tzafrir: Starting (SMI_EnableMmio)
(==) SMI(0): Tzafrir: in if() (SMI_EnableMmio)
(==) SMI(0): Tzafrir: After vgaHWSetStdFuncs (SMI_EnableMmio)
So it basically segfaults at the first outb() in SMI_EnableMmio().
