2.2.17 Lockup and ATA-66/100 forced bit set (WARNING)

2.2.17 Lockup and ATA-66/100 forced bit set (WARNING)

[Michael B. Allen]

I've enabled the higher performance features for my ATA drive by getting
2.2.17, applying Andre Hendrick's IDE patch, adding:

  append="idebus=66 ide0=ata66"

to lilo.conf. I was told that Alan's patches from here:

  ftp.kernel.org/pub/linux/kernel/people/alan

should be used. Is this true if I used Andre's patch? Is the warning
message in my bootlog anything to worry about? The board is an ABIT KT7A
w/ KT133A chipset.

Also, the machine locked up once (hard, couldn't connect via network). I
am using the Matrox G450 beta driver with XF 4.0.2 though. Maybe that
was the cause?

Thanks,
Mike

Alan = kernel, Andre = IDE.  2.2.18 (kernel) + ide.2.2.18.1221 (IDE
patch) + 2.2.19pre8 (kernel patch).  See samples below.

Ensoniq AudioPCI (ES1370) was problematic if I tried to assign IRQ5 on
the KA7 (hard trailess lockups, all IRQ's migrated to 10 or 11
regardless of config, digital audio ScreamOfAgony), whereas IRQ 3 worked
fine.  Similar experiements with Intel chipset boards P3B-F & BP6 suffer
no such issues so I assume it's VT82C686/ES1370 specific.

Ah, well I just added that based on the end of this boot message:

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

If I don't add it hdparm -t /dev/hda reports:

 Timing buffered disk reads:  64 MB in 16.46 seconds =  3.89 MB/sec

Then if I do hdparm -d1 -X66 /dev/hda I get:

/dev/hda:
 setting using_dma to 1 (on)
 setting xfermode to 66 (UltraDMA mode2)
 using_dma    =  1 (on)

[root@nano /root]# hdparm -t /dev/hda

/dev/hda:
 Timing buffered disk reads:  64 MB in  4.04 seconds = 15.84 MB/sec

Now if I add it via append, reboot and do hdparm -t I get:

 Timing buffered disk reads:  64 MB in  3.70 seconds = 17.30 MB/sec

This last difference is consistently better. Weird.

All your other bets were right too.

Thanks Wayne,
Mike

It's an old old bug with the ide-scsi lun probing code. Dont know if 2.4.x
fixed it yet. Solution -- disable lun probing in scsi config.
