Problem Description: The pata_sis module causes all kinds of issues when in use and going through this layer to access the HDD and CDROM results in the output below. Interestingly however the older IDE layer driver "sis5513" works perfectly. ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata4.00: cmd a0/01:00:00:00:fc/00:00:00:00:00/a0 tag 0 dma

newly developed pata drivers over the older ide layer where available, so trying to boot off for example an Ubuntu Hardy live CD will generate these errors from either the CDROM or HDD as it uses the new PATA layer to access the underlying devices. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for
