Subject: 2.5.54: ide-scsi still buggy?
Date: Wed, 8 Jan 2003 02:40:05 +0100 [thread overview]
Message-ID: <20030108014005.GC725@mail.muni.cz> (raw)
Hello,
ide-scsi emulation does not work for drive /dev/hdg, why?
kernel boot parameters:
kernel /boot/vmlinuz-2.5.54bk3 ro root=/dev/hda1 ide=reverse vga=4 hdg=ide-scsi
It freezes kernel (sysrq do nothing) after lines:
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: TEAC Model: CD-W512EB Rev: 2
Type: CD-ROM ANSI SCSI revision: 02
scsi scan: host 0 channel 0 id 0 lun 0 identifier too long, length 60, max 50. Device might be improperly identified.
while attaching it to /dev/hde works ok. Why?
