Hi, I'm very sorry, but I think I found another ATA problem: The problem occurs on a FUJITSU-SIEMENS E-series Laptop (E4010) with an Intel ICH4 UDMA100 Controller. This Laptop has two ATA-devices, a FUJITSU MHT2040AT disk ('ad0', without any problems!) as ata0-master (UDMA100) and a CDRW-device 'acd0' <UJDA750FDVD/CDRW> as ata1-master (PIO4). This CDRW-device is properly detected with a GENERIC 5.2.1-RC kernel of 'Sat Jan 31 05:36:22 GMT 2004' from freebsd.org. With a -current kernel GENERIC of 'Thu Feb 12' this kernel panics if the CDRW-device is *not* removed (i.e is present): The last messages I can see are: -----------------------8><-------------------------------- [...] cbb0: PC Card activation failed ad0: 38154MB <FUJITU MHT2040AT> [77520/16/63] at ata0-master UDMA100 ata1-slave: FAILURE - ATAPI_IDENTIFY no interrupt ata1-slave: FAILURE - ATAPI_IDENTIFY no interrupt acd0: CDRW <UJDA750FDVD/CDRW> at ata1-master PIO4 Mounting root from ufs:/dev/ad0s2a Loading configuration files.
