Subject: Ghost EDD devices in /sys again
Date: Fri, 5 Sep 2008 22:19:43 +0400 [thread overview]
Message-ID: <200809052219.44093.arvidjaar@newmail.ru> (raw)

This is regression but old enough. Apparently I had for whatever reasons
EDD turned off till recently. This is 2.6.27-rc5 just in case.
In 2006 I fixed ghost devices due to buggy BIOS:
http://marc.info/?l=linux-kernel&m=114087765422490&w=2
Later edd.S has been rewritten in C, and apparently this patch has been
lost:
{pts/1}% ls /sys/firmware/edd
int13_dev80/ int13_dev84/ int13_dev88/ int13_dev8c/
int13_dev81/ int13_dev85/ int13_dev89/ int13_dev8d/
int13_dev82/ int13_dev86/ int13_dev8a/ int13_dev8e/
int13_dev83/ int13_dev87/ int13_dev8b/ int13_dev8f/
But I have just a single disk. This is the same system BTW.
Unfortunately I do not speak asm language of C; if somebody could provide
equivalent fix for current edd.c, I am more than ready to test it.
Thank you
