Hello Jeff,

Yes it is. I'll keep testing with previous kernels.

Dmesg does look different with 2.6.23 vs 2.6.24-rc2

This is 2.6.23 :

scsi8 : pata_jmicron
scsi9 : pata_jmicron
ata9: PATA max UDMA/100 cmd 0x000000000001c000 ctl 0x000000000001c102 bmdma 0x000000000001c400 irq 17
ata10: PATA max UDMA/100 cmd 0x000000000001c200 ctl 0x000000000001c302 bmdma 0x000000000001c408 irq 17
ata9.00: ATAPI: BENQ    DVD DD DW1640, BSRB, max UDMA/33
ata9.00: configured for UDMA/33
ata9: EH pending after completion, repeating EH (cnt=4)
scsi 8:0:0:0: CD-ROM            BENQ     DVD DD DW1640    BSRB PQ: 0 ANSI: 5


This is 2.6.24-rc2 :

scsi8 : pata_jmicron
scsi9 : pata_jmicron
ata9: PATA max UDMA/100 cmd 0xc000 ctl 0xc100 bmdma 0xc400 irq 17
ata10: PATA max UDMA/100 cmd 0xc200 ctl 0xc300 bmdma 0xc408 irq 17
ata9.00: ATAPI: BENQ DVD DD DW1640, BSRB, max UDMA/33
ata9.00: configured for UDMA/33
scsi 8:0:0:0: CD-ROM BENQ DVD DD DW1640 BSRB PQ: 0 ANSI: 5
