Re: [Nouveau] [REGRESSION] nouveau: 30 second boot hang after commit 2b700825e

2015-08-09 Thread Eric Biggers
Hi, I am testing Linux v4.2-rc5 and I am sporadically getting crashes shortly after startup in gk104_fifo_intr_runlist(). What I've found is that the 'mask' value read from offset 0x2a00 comes back as '0xbad0da00'. This causes the 'engn' variable to be assigned the value 9, which is invalid; the
