Since 2.6.35-rc2 the USB keyboard driver don't work longer, on different mainboards and keyboards. On 2.6.35-rc1 things still were (more or less) normal. THIS IS AN ERROR WHICH ENTERED BETWEEN 2.6.35 -rc1 and -rc2 !! werner landgraf

The address 07200720 looks like a couple of gray spaces in a vga console and I've seen that before not long ago. After a bit of searching, I've found it: it's in the thread that started with "Linux 2.6.35-rc2", and most importantly in the thread: BUG kmalloc-4096: Poison overwritten (2.6.35-rc2) where there is a patch that is supposed to fix this. I thought this was already applied upstream, though... For your convenience, the patch in that thread is this one (might be white space mangled, as I just copy+pasted it, so you might need to apply it by hand): --- drivers/char/vt.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/char/vt.c b/drivers/char/vt.c index 1296c42..e123958 100644 --- a/drivers/char/vt.c +++ b/drivers/char/vt.c @@ -304,8 +304,8 @@ static void scrup(struct vc_data *vc, unsigned int t, unsigned int b, int nr) d = (unsigned short *)(vc->vc_origin + vc->vc_size_row * t); s = (unsigned short *)(vc->vc_origin + vc->vc_size_row * (t + nr)); scr_memmovew(d, s, (b - t - nr) * vc->vc_size_row); - scr_memsetw(d + (b - t - nr) * vc->vc_size_row, vc->vc_video_erase_char, - vc->vc_size_row * nr); + scr_memsetw((void *)d + (b - t - nr) * vc->vc_size_row, + vc->vc_video_erase_char, vc->vc_size_row * nr); } static void scrdown(struct vc_data *vc, unsigned int t, unsigned int b, int nr) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I compiled 2.6.35-rc3-git7 applying this patch, but the problem continues. I have an USB keyboard and mouse. For BIOS and lilo the keyboard works normally. However, when the kernel loads, it stops imediately. I can check this by pressing repeatedly the key lock and observing when the light don't blink. On -rc2 came arbitrarily characters (but only 1 por line) on the text screen. A PS2 keyboard blocks completely as explained above (and also the PS2 mouse t dont work), an USB keyboard worked almost normally in the grafic mode(also the PS2 mouse worked), But on -rc3 , no kind of keyboard didn't work anymore. Rebooting with 2.6.35-rc1, everything works normal. Thus, the error entered between -rc1 and -rc2 , on something what was changed also till -rc3 so that it then become more worse.
