Bug#768157: machine hangs when loading cirrus with modeset=1 while booted with vga=791
Package: src:linux
Version: 3.16.7-1
Severity: normal
Hi,
while testing the new Grml release, I noticed an interesting hang of QEMU when
the machine is booted. The initial testing was done using [1] in QEMU from Sid
(2.1+dfsg-5), but I also could reproduce it with the same QEMU and a fresh
Jessie install with both, 3.16.5-1 and 3.16.7-1.
To reproduce:
* boot a fresh Jessie with 3.16 kernel in QEMU and vga=791 as bootparam
* modprobe cirrus modeset=1
* machine hangs
I am not sure this will happen on real cirrus HW, as I don't have any, but QEMU
is quite widespread and cirrus is the default VGA driver.
Regards
Evgeni
