Hi,
I just switched to libata (pata) on my laptop and the immediate panic made it
impossible to figure out why my boot partition wasn't available.
After applying this little patch I could check boot printk output and then saw
everything was properly recognized and only scsi-disk support was missing.
The correct fix would be to make scroll back (and sysrq) still work
after panic. It's a little more complicated, but possible (essentially
it needs a polled keyboard handler)
Customer: "This system could not find the root fs."
Support: "Oh, yeah, just connect a (USB-) keyboard and scroll back."
Hmm, device detection works after panic?
I really like the "soft" panic better, where you still can operate the
kernel debugging features, but just have no user space supporting it.
Of course, if we'd been using kinit, "soft panic" would have been done
exclusively in userspace...
