Very Computer

I'm having problems getting Linux to correctly mount the IDE/ATAPI
Sony CDU77E (obviously with a CDROM in it).  I don't even see any activity  
on the status lights for the drive that might indicate and attempt to
mount the drive.

At boot up the kernel recognizes the drive, and tells me that it is hdc.
I try to mount it, and I get a stream of IRQ timeouts, which lead to
I/O errors.

Is anyone else having this problem?  

Thanks for any suggestions.

Try swapping for a different hard drive (really).  I noticed interraction
between my seagate ide and the atapi cdrom.  With a WD or Quantum the problem
went away.  Strange ...

Hi All...

I've read the faq, I've re-compiled my kernel (1.3.58) and I've tried
switching things around on the motherboard.  I have a CDROM that is properly
identified, that works wonderfully under DOS/WIN95 but causes the following
errors.  Can someone help me out?  I get similar errors under 1.2.13?  Is it
my hardware?

Thanks

I have a Sony CDU76E connected to the second IDE interface of a
Goldstar EIDE care (Prime2c chip). I experience the same thing. The
CD-ROM is correctly recognized at boot time as hdc (with the correct
model details etc so it must be talking to it somehow) , but the
message IRQ probe failed (0). Any attempt to access the drive results
in irq timeouts. The drive is jumpered to master (although I've tried
slave with the same results - except it was hdd of course).

The drive works under DOS, so I am at a loss for what to do next. Is
this a problems specifically related to the newer SONY ATAPI drives???

Did you have the CD-ROM on the same ide interface as the drive you were
using? I have a Samsung and a WD on the primary - I can't imagine how
they would interfere, but then again, stranger things have happened.

Any more suggestions, experiences etc?

Have you checked the major/minor device numbers for hdc?  They need to be 22/0

respectively.  If they aren't right it will not mount.  I have the same drive

and had the same problem.  Good Luck....

Could you say more about your setup? I have a CDU76E connected to the
secondary interface of an EIDE card, and while the drive is recognised
at boot time, I get an irq timeout. I have run MAKEDEV.ide, and besides
I don't think that the device numbers would be related to the irq
problem. I was wondering if there was any specific problem with these
newer SONYs that might be causing the irq timeout - especially since
the drive works fine under DOS.

Thanks,

Mark
