After beginning writing to cd, mem (cache) is growing rapidly and after about 15 minutes linux swaps enormous and the system gets unusable. After about 1 minute cdrecord gets no data anymore (it crashes) and the system is like it was before. These problems did not occure with 2.4.9. The following messages appear: Sep 26 18:44:49 adlib kernel: scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 1, lun 0 Synchronize Cache 00 00 00 00 00 00 00 00 00 Sep 26 18:44:49 adlib kernel: hdd: irq timeout: status=0xc0 { Busy } Sep 26 18:44:49 adlib kernel: hdd: DMA disabled Sep 26 18:44:49 adlib kernel: hdd: ATAPI reset complete Sep 26 18:44:49 adlib kernel: hdd: irq timeout: status=0x80 { Busy } Sep 26 18:44:49 adlib kernel: hdd: ATAPI reset complete Sep 26 18:44:49 adlib kernel: hdd: irq timeout: status=0xd0 { Busy } I use ide-scsi and /dev/hdd == /dev/scd1 == /dev/cdwriter.
