User-Agent: Mozilla/4.76 [en] (X11; U; SunOS 5.6 sun4u)


I have a machine with 1GHz Athlon, 45MB hdd, a 40x CD-rom, and Zip drive.

P.Master:	HDD
P.Slave:	Zip Drive
S.Master:	CD-ROM

If I boot the machine without a zip disk in the drive, I get:
hda: [drive specs]
hdb: [long pause, then] lost interrupt
lost interrupt
lost interrupt
lost interrupt
.
.
.

This goes on until I give up and either:
a) put in a zip disk and reboot, or
b) power down, remove the zip drive, and power back up.

The system boots quite happily if there is a disk in the drive.

[Sorry if this is a dup, I couldn't find any other bug report that matched
it....]



Reproducible: Always
Steps to Reproduce:
1.  Make sure there is no zip disk in internal zip drive
2.  Power up the machine
3.  Wait.  The machine will hang as described above.

	

Actual Results:  See description section above.

Expected Results:  The system should boot quite happily whether there is a
disk in the zip drive, or not.  RH5.2 booted as expected.  I don't recall,
but I believe 6.2, acted like 7.0.

This is rather annoying.  If you can provide some insights on how to track
it down, I don't mind being a guinea pig.

Confirmed same symptoms on fisher. Need zip disk in drive to bypass.

Test platform is a Micron Millennia Pro2 (P2/200). borgan, johnsonm, I've no 
idea how to link this bug into the fisher project. Sorry.

Doug, could this be hanging in lun probing?  If so, can you add this
to the lun probe blacklist?

Comment 3 Paul Raines 2002-02-06 18:16:40 UTC

I believe this behavior is due to a particular version of the zip drive.
I have nearly identical systems running the same kernel, but one hangs and
one doesn't if there is no zip in the drive.  If I swap drives, the behavior
follows the drive.  THe drive works fine in Windows so there is obviously
some solution to this

Should work in 2.4.18 and higher reliably. If not please re-open
