Re: Re: any 2.6.x kernel for a DS10 with NCR 53C895 and QLogic ISP10x0 ?

I have a 53C895 in my PWS, running Norbert's 2.6.8, no problem.

The problem is that ext3 doesn't work because of a compiler bug in gcc-3.3 (#261893)

Loading the ext3 module causes a kernel OOPS, after which the module is still loaded, but ext3 is obviously not supported.

I have only XFS on my PWS, so I don't see the problem, as long as I force ext3 out of the initrd. The reason is that, instead of looking in /etc/fstab for the fstypes of the various partitions, the initrd tries just any supported fstype in alphabetical order. since ext3 is before xfs, I was still seeing OOPSes, even though I'm not using ext3 anywhere.


Same exact problem on my DS20L machines, I had to drop back
to 2.6.5-1-smp (obsolete but stable).

I tried your suggestion, doing an 'apt-get install

The system did boot all the way up on the new kernel after hanging
for an extended period of time attempting to launch syslogd.

However, now I have a strange new problem.  The system refuses to
mount /var because it is an 'ext3' partition.  But the root partition
is an ext3 partition, and it *is* mounted.  The console log shows the
following relevant message:

   EXT2-fs warning (device sde5): ext2_fill_super: mounting
ext3 filesystem as ext2

but then goes on as normal with everything, even saying that
/var is clean:

   INIT: version 2.86 booting

The subsequent mount listing is

   fchelp:~# mount
   /dev/sde5 on / type ext3 (rw,errors=remount-ro)
   proc on /proc type proc (rw)
   sysfs on /sys type sysfs (rw)
   devpts on /dev/pts type devpts (rw,gid=5,mode=620)
   tmpfs on /dev/shm type tmpfs (rw)
   /dev/sde4 on /boot type ext2 (rw)
   fchelp:~# df

   /dev/sde4               122835     15565    100717  14% /boot

But no /var mount is allowed:

   fchelp:~# mount /var
   mount: fs type ext3 not supported by kernel
   fchelp:~# uname -a
   Linux fchelp 2.6.8-1-generic #1 Tue Aug 17 08:46:31 CEST
2004 alpha GNU/Linux
   fchelp:~# date
   Mon Aug 30 14:55:03 EDT 2004

How was the root partition 'forced' into ext2 mode?  Can I do the same
with /var, or must I redo everything as ext2?  Do I have
another alternative
(XFS, JFS, etc.) that will work better for root or /var or both?

Thanks again,
