Hi!
On my hp nx7300 laptop, 2 following scenarios can happen during bootup
(see attachments for the full logs): the "good" one [1] and the one
where multiple EHs lead to limiting the speed [2].
[1] one is more rare, but it seems to be persistent over reboots: once
it happened, just rebooting the machine always results in behaviour
like [1].
[1] results in a working cdrom from the start. An attempt to use cdrom
after [2] happened results in even more EHs, resulting in "configured
for PIO4", after which the cdrom is finaly working.
The version I'm using is 2.6.23-rc6, but the same used to happen with
the previous rc's, and probably with 2.6.22 too (I can check).

I've just built 2.6.22.6 with basically the same configuration, and
the behaviour is just the same, i.e. both [1] and [2] still can
happen.

Hmmm... Is MWDMA2 mode used with ide driver too?

Yes, that's MWDMA2. Hmm... We're seeing many cases where MWDMA doesn't
work with libata while it works fine with IDE but have no idea what's
going on yet. :-(

Okay, thanks. Please feel free to contact me if you need any more testing done.

This may be well a hardware problem. Same laptop (HP nx7300 GB848ES)
works fine with either 2.6.22 and 2.6.23-rc. Maybe actually using the
DVD is required to trigger the problem on the next reboot?
Sergey, btw, on this laptop I've observed lockups twice with the -rc5.
After switching to 2.6.22 it was stable for at least one day. Can you
confirm or refute this?

No, that is not required. The problem shows up on a fresh start from
powered-off state just as well.

I've been using 2.6.23 rcs (rc3, rc6) since August, often for days
without rebooting the machine. Haven't seen any lockups (except the
ones on a return from suspend-to-RAM, but that's another story).
