Subject: PATA_WINBOND lost interrupt - linux-2.6.36.2 - ppc64
Date: Mon, 3 Jan 2011 13:08:38 +0100 [thread overview]
Message-ID: <20110103130838.34f34218.acrux_it@libero.it> (raw)
hi,
there is a problem using new pata drivers with an old IBM Intellistation POWER 275 (9114-275 pSeries POWER4+).
These boxes are equipped with an IDE dvd-rom drive (PATA_WINBOND driver).
0000:00:03.1 IDE interface: Symphony Labs SL82c105 (rev 05)
I can report, instead, that the old ide-cd driver BLK_DEV_SL82C105 (i tested the same scenario but with linux-2.6.32.7) works fine. Obviously it happens only when boot or try to read from the dvdrom drive.
