Description Arlinton Bourne 2007-05-23 14:34:08 UTC 
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):
2.6.21-1.3163.fc7

How reproducible:
Always

Steps to Reproduce:
1.Boot kernel (f7 kernel)

  
Actual results:
Kernel Panic

Expected results:
Welcome to Fedora

Additional info:
Workaround, compile the legacy driver

Stay tuned for screenshots...

Comment 7 Hans de Goede 2007-06-10 11:22:29 UTC 
There is an F7 kernel-update candidate available here:
http://people.redhat.com/davej/kernels/Fedora/fc7/RPMS.kernel/

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
kernel.

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
