Summary: xorg hangs at boot only with vesa driver and quiet
kernel parameter
Product: xorg
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Driver/intel

dmesg output

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated
Graphics Controller (rev 02) (prog-if 00 [VGA controller])
Subsystem: Lenovo Core Processor Integrated Graphics Controller
Flags: bus master, fast devsel, latency 0, IRQ 32
Memory at f2000000 (64-bit, non-prefetchable) [size=4M]

Capabilities: <access denied>
Kernel driver in use: i915
Kernel modules: i915
Model name: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz
This started with 5.2 and still goes on with 5.2.5
If the 'quiet' kernel parameter is omitted, the system starts normally.
If it's not omitted, then it's a hard hang, and X wouldn't start.
It also works fine after a wakeup by suspending the system.
Disabling wireless connection from the bios made no difference. Only enabling
log messages on the kernel parameter does.
Also, video-intel seems not affected by this.
