HP CD-RW hangs my machine when mounting it!!!!

Post by Simon Tet » Tue, 25 Jul 2000 04:00:00



Hi, I just bought a HP Cdwriter+ 8200 series (8250i)
and I enabled the scsi modules in my kernel so it is recognized properly

but if I try to mount it, it seeks the disk for a second or two and
hangs my machine.. everytime!
(I have to power it down to reboot)

Though I can listen to Audio CD without problems...

Anybody got an idea??

Here's my config:

HP CD-RW hangs my machine when mounting it!!!!

Glad you got it working.

One thing I'd suggest, though, on this drive. The HP 8250i was actually
OEM'd by two different manufacturers, Sony and Philips. You can tell
the difference by looking at the front panel of the drive. The Philips
drive has a hinged front door that swings down when the tray ejects and
a row of six* or so small slots along the bottom edge of the drive;
the Sony has a front door that is actually a part of the tray and
travels
with the tray when it ejects, and has no slots. A word to the wise; if
you have the Philips-made drive, take it back to the vendor and swap
it for one of the Sony-made drives. The Philips drive has a firmware
problem that causes the drive to lock up and refuse access if you leave
it idle long enough for the motor to spin down. There appears to be no
fix for this problem. I had a Philips-made drive, and I had no end of
problems with it under Linux, Win95, and WinNT if I happened to leave
a disc in long enough to spin down. I took it back to the vendor where
I bought it, explained to them nicely that research on the Internet
revealed this design problem, and asked to trade it in for a Sony-built
drive. As the drive was under warranty, they agreed. I am very happy
with the Sony-built drive.

 
 
 

1. mounting cd-rw hangs kernel

Hi all,

When I try to mount my cdrw, the kernel hangs. I have to power down in order
to get control back. This happened with iso9660 and joliet CDs, didn't try
other ones.

This is a customized kernel (2.4.20).

Basically, it has full ide support (all statically linked), and scsi support
for scsi emulation.

The Scsi options (everything not mentioned is not set):

CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRA_DEVS=40
CONFIG_BLK_DEV_SR=y
CONFIG_SR_EXTRA_DEVS=2
CONFIG_CHR_DEV_SG=y
CONFIG_SCSI_DEBUG_QUEUES=y
CONFIG_SCSI_MULTI_LUN=y

generic IDE options (everything not mentioned is not set):
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_IDEDISK_STROKE=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDETAPE=y
CONFIG_BLK_DEV_IDEFLOPPY=y
CONFIG_BLK_DEV_IDESCSI=y

File system options (everything not mentioned is not set):
CONFIG_REISERFS_FS=y
CONFIG_EXT3_FS=y
CONFIG_JBD=y
CONFIG_JBD_DEBUG=y
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_UMSDOS_FS=y
CONFIG_VFAT_FS=y
CONFIG_TMPFS=y
CONFIG_RAMFS=y
CONFIG_ISO9660_FS=y
CONFIG_JOLIET=y
CONFIG_ZISOFS=y
CONFIG_JFS_FS=y
CONFIG_JFS_STATISTICS=y
CONFIG_NTFS_FS=y
CONFIG_PROC_FS=y
CONFIG_EXT2_FS=y
CONFIG_UDF_FS=y

I have two cd drives in the box, one dvd reader, one cd burner, all ide.
The drives are recognized:

<4>hda: MAXTOR 4K080H4, ATA DISK drive
<4>hdc: Pioneer DVD-ROM ATAPIModel DVD-106S 012, ATAPI CD/DVD-ROM drive
<4>hdd: SAMSUNG CD-R/RW SW-408B, ATAPI CD/DVD-ROM drive

And for the cd burner, scsi emulation is enabled:

<6>SCSI subsystem driver Revision: 1.00
<6>scsi0 : SCSI host adapter emulation for IDE ATAPI devices
<4>  Vendor: SAMSUNG   Model: CD-R/RW SW-408B   Rev: BS02
<4>  Type:   CD-ROM                             ANSI SCSI revision: 02
<4>Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
<4>sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray

Now, when I mount something with the dvd reader, everything works.
When I mount a cd in the burner, the system hangs.

Thanks for any help.

bye thomas
