[Qemu-devel] Fedora Core 2 2.6.5 kernel hang during bootup (IDE probe?)

[Lennert Buytenhek]

Hi,

When trying to install Fedora Core 2, the IDE probe takes a _really_ long
time to complete.  It takes about 10 seconds before it displays
"hda: QEMU HARDDISK, ATA DISK drive", and then it takes at least a minute
or two before it displays "hdc: QEMU CD-ROM, ATAPI CD/DVD-ROM drive".

Just before that, it mentions this, though:

        Losing too many ticks!
        TSC cannot be used as a timesource.
        Possible reasons for this are:
          You're running with Speedstep,
          You don't have DMA enabled for your hard disk (see hdparm).
          Incorrect TSC synchronization on an SMP system (see dmesg).

It's still paused (after displaying hdc: blah) right now, with qemu at 99%
CPU.  I'll wait for a while to see if it ever gets through this stage at all.


cheers,
Lennert
