[ltp] libata PATA drivers on ThinkPad T42
Wed, 14 Mar 2007 21:20:25 +0100
Anyone tried to use libata PATA drivers on an IBM ThinkPad T42?
I felt adventurous to compile a 220.127.116.11 + ck1 patchset + sws2 18.104.22.168
today with libata PATA drivers.
I additionally activated these config options:
CONFIG_PATA_MPIIX=y (this should be the right one according to wikipedia
Intel IO Hub list)
And thought of trying it out with:
# kopt=root=/dev/sda1 ro resume2=swap:/dev/sda5 resume=/dev/sda5 vga=792
I AFAIFO (as far as I found out) could switch back to old ATA drivers with
if need be:
# kopt=root=/dev/hda1 ro resume2=swap:/dev/hda5 resume=/dev/hda5 vga=792
But all of this is quite some guess work. I did not found more about it
than this little paragraph in kernel parameters:
combined_mode= [HW] control which driver uses IDE ports in
mode: legacy IDE driver, libata, or both
(in the libata case, libata.atapi_enabled=1 may be
useful as well). Note that using the ide or
options may affect your device naming (e.g. by
changing hdc to sdb).
Format: combined (default), ide, or libata
Any hints? Anyone tried it yet? Is it working stable? Will try to compile
the new kernel now, but will stay with "combined_mode=ide" first.
