The pause is expected, but shouldn't be _that_ long, it seems some
problem is triggered by the errata workaround for those chips. If you
edit drivers/video/radeonfb.h, and comment out that bit of code:
/* we can't deal with posted writes here ... */
In the definition of radeon_pll_errata_after_data(), the pause will go
away. Does it have any effect on your crashes ?
