2.4.19-pre3 IDE-problem

2.4.19-pre3 IDE-problem

Post by jarau.. » Thu, 14 Mar 2002 02:00:16



Hi all

on my Supermicro Serverworks board
with ide-scsi emulation 2.4.19-pre3 hangs
when accessing the IDE-ZIP drive (at Serverworks IDE)
(2.4.18 with the IDE is OK)

Although I configured DMA for disks only
I get
ide_dmaproc: chipset supported ide_dma_lostirq func only: 13
hdd: lost interrupt  (that is a new ATA 133 Maxtor disk at a Promise IDE
controler)

Serverworks OSB4 in impossible state
Disable UDMA ....

(I have already applied the bluesmoke patch posted)

Thanks for looking into it

1. Promise 20267 hangs with 2.4.19-pre3 and 2.4.19-pre3-ac3

With 2.4.18 everything works fine:

  Mar 13 13:56:13 athlon kernel: PDC20267: IDE controller on PCI bus 00 dev 48
  Mar 13 13:56:13 athlon kernel: PDC20267: chipset revision 2

  Mar 13 13:56:14 athlon kernel: hdf: 268435455 sectors (137439 MB) w/2048KiB Cache, CHS=266305/16/63, UDMA(100)

  Mar 13 13:56:14 athlon kernel:  hde: hde1 hde2 hde3 hde4
  Mar 13 13:56:14 athlon kernel:  hdf: hdf1

With 2.4.19-pre3 and pre3-ac3 the disk type and size are reported correctly
but the systems hangs at the partition check (I couldn't find a copy of the log on
the disk so I edited the above to match what I remembered on the screen):

  Mar 13 13:56:13 athlon kernel: hde: Maxtor 4G120J6, ATA DISK drive
  Mar 13 13:56:14 athlon kernel: hde: 240121728 sectors (122942 MB) w/2048KiB Cache, CHS=238216/16/63, UDMA(100)
  Mar 13 13:56:14 athlon kernel: Partition check:
  Mar 13 13:56:14 athlon kernel:  hde:

I tried the experiental ide timeout workaround and that does print a timeout message
after a few seconds but the system still hangs there.

Its a Tyan 2462 athlon SMP with real SMP CPUs. There is another disk and a cdrom on
this controller but due to cable lengths I can't switch things around.

I am willing to try any patch or suggestion...
