hang on mount, 2.4.2-pre4, VIA

[Dan Christian]

Hello,
  I just tried upgrading to 2.4.2-pre4 from 2.4.1 and get a hang when
mounting the file systems.  I have the same problem with 2.4.1-ac18.

The system is a single processor P3 and uses a VIA chipset (Tyan
something-or-other).  DMA, multi-sector IO, and 32bit sync are enabled
using hdparm (just before the hang).  There are two Ultra-66 drives
attached to one IDE channel and a CD-RW on a second IDE channel.

The distribution is RH7 with recent security patches and modutils
2.4.2.  The kernel was built with kgcc.

Has anybody else seen this?

I'm not on the list.  Please CC me on any replies.

-Dan

Remove the hdparm command. It isn't needed.

I assume these problems weren't present before?

What's your southbridge chip (lspci ...)? What are the drives (hdparm -i ...)?

I can send you the VIA latest drivers if you are interested in trying
whether they'll help.

Some more info.  I tried disabling the hdparm command, that didn't
make the 2.4.2-pre4 mount succesfully.

I tried 2.4.2-pre1 and that booted fine.

I'll try pre2 and pre3 versions when I get a chance (thursday night)
and see about turning up the log level, too.

Here is the info on PCI and the drives.  I edited out the sound, scsi,
usb, etc.

Have you tried to set LOGLEVEL in /etc/sysconfig/init to something higher
(8)? That way you may see what is happening, instead of just getting a
kernel freeze.
