Red Hat Bugzilla – Bug 240966
Pata-ALI drivers broken, disk partitions are not detected
Last modified: 2007-11-30 17:12:05 EST
Description of problem:
Using the pata-ali drivers (libata) on the latest kernel (at the time -
2.6.21-1.3163.fc7) results in a kernel panic - not being able to mount root.
It seems after the kernel finds the hard drive and then is probing for the hard
disk's partitions it prints something about being 'frozen' then does a soft reset.
So boot -> detect drive -> finds drive -> finds no partitions -> kernel panic (i
can't mount root)
Note this is not a regression, as I've tried this with various rawhide kernels.
pata-ali never worked on this machine (fujitsu p series lifebook p1120).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot kernel (f7 kernel)
Welcome to Fedora
Workaround, compile the legacy driver
Stay tuned for screenshots...

There is an F7 kernel-update candidate available here:
Which amongst other things contains a fix for ALI IDE problems. Please try this
kernel and report back how it works for you.
Always be carefull when testing new kernels. Use rpm -ivh to install the new
kernel besides your current one so that you can always boot back into the old
I've installed kernel-2.6.21-1.3232.fc7.i586.rpm
The kernel did not panic and the system booted
So far so good.
Patch was in released kernel 1.3228.fc7
