Hi Folks,
I am in need of some fairly serious help here.
I am attempting to run RedHat 7.2 with a 2.4.17 kernel with Andre
Hedrick's IDE patches
dated 1/29/02 on a Pentium 4 on an MSI motherboard with an Intel I845
chipset (MB model
MS-6528LE, socket 478) and 512 MB PC133 SDRAM. Onboard IDE supports UDMA
66 and 100.
Onboard AGP and sound is disabled, video card is Kaser S64P PCI with
SIS6326, 8 MB RAM,
3COM 3C595 present but not in use. Generic 1.44MB floppy and ATAPI
CD-ROM also present.
Originally, hard drive was Western Digital WDC WD400BB-00AUA1 (40 GB)
but I needed my
production system so I had to recreate problem using a Western Digital
WDC AC22100H.
Original symptoms include:
1. unable to complete badblocks during install, terminated with Oops
2. unable to copy large (50-150 MB) files/directories to HD from CD-ROM,
cp, tar, etc.,
terminated with Oops and file corruption
3. idle system running X and screensaver dies overnight with Oops and
file corruption
By file corruption, I mean massive: dozens to hundreds of files and MB
lost. MTBF was
approximately one hour in most cases.
Embarassingly enough, Windoze 98 SR2 installs and runs fine on same
hardware with no
apparent problems. Memtest86 2.5.1 runs with no errors. So, with the
understanding that
Windoze does not beat hardware up like Linux does (ie., does not make
the best use of it),
I feel like my hardware is functioning normally.
In order to get my production system running and still be able to
document the problem for
this bug report, I was forced to use a lesser quality hard drive, but
the symptoms are
unchanged. Because of repeated Oops while loading the software, I
eventually ended up doing
the following:
1. install minimal RedHat 7.2 on a partition of production system
2. build minimal kernel on production system for Pentium 4 system
3. make bootable cd-rom which is a copy of minimal system and runs in
single-user mode
4. install with separate partitions for /, /dev, /tmp, /var, /usr; in
this way, I was
able to run with / and /usr read-only (most things work OK) and not
spend more
time rebuilding damaged filesystems than getting this bug report
together
(SUGGESTION: it would be nice if things like time drift adjustment files
and device
files created on the fly for socket pipes, etc., could be kept in /var -
then you
could run with the majority of the system read-only (except /var and
/home, for instance)
and be much less vulnerable to bugs and power problems, not to mention
it might be an
initial defense against script-kiddies)
5. recreated Oopses as follows: ran script (below), output of which
shows data corruption
in pass 1 before Oops in pass 2; Oops in sync preceded Oops in kupdated;
SysRq did nothing
for me, and Ctrl-Alt-Del resulted in Oops on each attempt.
The documentation for this bug report follows. I have tried to make it
complete and readable.
If anyone has any suggestions or patches please respond to me
individually as well as to
the listserver (I don't subscribe, but I do read it when I have the
time).
At this point, I have spent $500 for the MB, CPU, SDRAM and video card
and it is useless
to me until I can get linux to run reliably. If I have shot myself in
the foot somehow,
I am missing it, but I think we really have a problem here. The original
purchase was for
video mjpeg capture using DC10+ (which had noise problems with my FIC MB
using VIA chipset),
so when I found that Pinnacle only supports DC10+ for Intel MBs, I got
this setup. I hate
to think I'll have to run Windoze to do my project.....
Any and all suggestions welcome; Thank you for reading (and helping,
hopefully!).

The kernel inlines stuff too much, and we're sloshing
vast amounts of stuff across the memory bus needlessly.
I suspect this is a more important issue than all the
stupid FASTCALL, likely() and `goto out_of_line' crud.
I chose to inline __wake_up_common() when I did the
try_to_wake_up() stuff because __wake_up_sync() is almost
never used, and the only other call site was __wake_up().
But now complete() is there too, Its main use will be in
disk driver calls - things like IDE CDROM where `ide_wait'
is used. Also SCSI uses complete() for synchronous operations
such as ioctls, disk spin-up, etc. I don't think scsi
uses complete() on a common path.
So __wake_up() remains the single main user of
__wake_up_common(), so __wake_up_common() should remain inline.

Hi Folks,
Well, I guess I'm not the only one who has ever had egg on his face
after posting a bug report.
Before posting the report, I had run memtest86 v2.5.1 for more than one
complete pass of the std tests and had concluded the memory was OK. On
a hunch, after a reply from Mark Hahn, I let it run all night; after 17
hours running all tests over 3+ passes, it recorded about 4000 errors.
These were clustered around 64MB and 135MB (64K and 4K holes,
respectively), and I think that adequately accounts for the problems I
was having on large file copies. The guy who sold me the hardware took
it all back and refunded my money rather than having to learn something
about linux, so I guess he didn't deserve the sale after all.
Thanks again to all who read and responded. Now I know to run multiple
passes on memtest before deciding things are OK....

Does it do it without Andre's patches ?
