>Description:
hi there,

i was trying to create an iso from a cd. i tried both dd and recoverdisk.
unfortunately during the very last read i get the following warnings:

interrupt storm detected on "irq19:"; throttling interrupt source
interrupt storm detected on "irq19:"; throttling interrupt source

acd0: FAILURE - READ_BIG timed out

during the interrupt storm the whole system freezes. what's strange about this
is that this only happens with recorded cds. when i use dd or recoverdisk with
a retail cd i'm having no problems at all. i tested this with cds that got
recorded under freebsd (using burncd) as well as with cds recorded under
windows. the results is the same (being the interrupt storm). the problem
however does NOT exist with DVDs or DVD-/+R's! only with CD-Rs!

this is the controller i'm using:

<JMicron JMB363 SATA300 controller> port
0xd000-0xd007,0xd100-0xd103,0xd200-0xd207,0xd300-0xd303,0xd400-0xd40f mem
0xf8000000-0xf8001fff irq 19 at device 0.0 on pci3

the drive is pata:

DVDR <HL-DVDR <HL-DT-ST DVDRAM GSA-H10N/JL12> at ata4-slave UDMA33

also i'm getting the following warnings during the boot process:

acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01

cheers.
