Description Alexander Martynenko 2015-02-25 13:52:34 CET

Description of problem:

Laptop Acer 2509 hangs while try to reboot, poweroff; 
randomly hangs while booting.

How reproducible:

Install Mageia Cauldron on Acer 2509.

Way to fix the problem:

I found the same problem with Dell Inspiron 11-3147, described in:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1341925
This issue seems to be caused by a buggy driver for the Synopsys Designware I2C DMA controller. Need to blacklist the dw_dmac and dw_dmac_core kernel modules in 
/etc/modprobe.d/blacklist-mga.conf

After blacklisting modules all works fine.



Reproducible:

Thomas, can you comment? In any case looks like a candidate for Errata (and maybe an update later)

Whiteboard: (none) => MGA5TOO FOR_ERRATA

Is this bug still valid for Mageia 6sta1 ?
