Red Hat Bugzilla – Bug 193532
libata and ata_piix cannot detect sata harddisk properly on acer travelmate 4150 ich6
Last modified: 2008-01-19 23:41:31 EST
Description of problem:
Kernel detects harddisks as ide. ata_piix loads up but does not detect sata
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot up with 'combined_mode=libata' appended to kernel cmdline and m
Machine stops booting when tryinig to detect harddisk partitions.
Machine should detect harddisk partitions and continue boot process.
The hdd shows up as secondary master and the
dvdrom drive is secondary slave on an ICH6. ata_piix loads up and doesnt detect
anything. I added 'combined_mode=libata' to the cmdline to get it to detect and
it found it as a sata hdd but it stopped booting at sda: <6> and then after a
couple of minutes, the machine just froze.
I have been trying various boot params to get it to work but it was no go. I
wanted to turn off 'libata.atapi_enabled' so I put in 'options libata
atapi_enabled=0' in modprobe.conf and then ran 'new-kernel-pkg --package kernel
--mknitrd --depmod -v --install 2.6.16-1.2122_FC5', but it didnt turn it off
when it booted up(linux-2.6-defaults-enable-sata-atapi.patch). I also tried
hdc=noprobe, trying to get ata_piix to hook on to the hdd but not the dvdrom,
and that resulted in hdd not being detected at all.
Finally, unscrewed dvdrom and pulled it out and machine booted up with
'combined_mode=libata' and ata_piixn works as long as theres no drive in the
bay. Im already floppyless... now Im cdromless too. ;-) Cannot do anything in
the BIOS to change things either. The FC5 BOOT kernel/installer also has the
