I've updates my -current system from Sep, 14th to todays -current (2
hours old). Now i cant boot further than detecting cdrom drives. After
testing my second cdrom (cdrw) for its UDMA capabilities the kernel
hangs in an endless loop. The output is a repeat from two lines which
are printed so fast i cant really read .... but it must be something
like that:

acd1: WARNING - REQUEST_UDMA .... (error request)
acd1: WARNING - INQUIRE_SENSE .... (retrying request)

The drive is an 2x2x24x CD/RW from Traxdata which is detected previously
as:

acd1: CDRW <CDRW2224 PLUS> at ata1-slave WDMA2

Jan

P.S: same with / without acpi....
