(c007894 is in "msr_vec_debug".)
I get the same trace. As Olaf Hering suggested, it's failing
when "giveup_altivec" is called. It looks like a processor version
check was recently added to "giveup_altivec" (in
arch/ppc/kernel/head.S) but it seems to be incorrect:
.globl giveup_altivec
giveup_altivec:
mfpvr r24 /* check if we are on a G4 */
srwi r24,r24,16
cmpwi r24,[EMAIL PROTECTED]
beq 3f /* continue */
mflr r24
bl msr_vec_debug /* debug thingy in process.c */
mtlr r24
blr
3:
...
I think PVR_7400 is the unshifted value? (Also, the TiPB uses a 7410,
so what is the right comparison?) Anyway, without this check, sleep
seems to be fine in both console and X11 mode.
