Hi, My system crashes sometimes (but keeps on going for days at a stretch if in good mood) and it does everytime because of problem with my hard-disk controller. I have checked the hard-disk and there is no problem with it. Hard disk is: Seagate ST3200822A Chipset is VIA686A Problem creator is Promice Disk Controller: PDC20265. If the information is not enough then I can provide more. Thanks Vijay Gill The log of last crash is as following Apr 2 17:00:13 dxr kernel: hde: DMA timeout error Apr 2 17:00:13 dxr kernel: hde: dma timeout error: status=0x50 { DriveReady SeekComplete } Apr 2 17:00:13 dxr kernel: ide: failed opcode was: unknown Apr 2 17:00:13 dxr kernel: hde: task_in_intr: status=0x51 { DriveReady SeekComplete Error } Apr 2 17:00:13 dxr kernel: hde: task_in_intr: error=0x04 { DriveStatusError } Apr 2 17:00:13 dxr kernel: ide: failed opcode was: unknown Apr 2 17:00:13 dxr kernel: hde: task_in_intr: status=0x51 { DriveReady SeekComplete Error } Apr 2 17:00:13 dxr kernel: hde: task_in_intr: error=0x04 { DriveStatusError } Apr 2 17:00:13 dxr kernel: ide: failed opcode was: unknown Apr 2 17:00:13 dxr kernel: hde: task_in_intr: status=0x51 { DriveReady SeekComplete Error } Apr 2 17:00:13 dxr kernel: hde: task_in_intr: error=0x04 { DriveStatusError } Apr 2 17:00:13 dxr kernel: ide: failed opcode was: unknown Apr 2 17:00:14 dxr kernel: hde: task_in_intr: status=0x51 { DriveReady SeekComplete Error } Apr 2 17:00:14 dxr kernel: hde: task_in_intr: error=0x04 { DriveStatusError } Apr 2 17:00:14 dxr kernel: ide: failed opcode was: unknown Apr 2 17:00:14 dxr kernel: Badness in pdc202xx_reset_host at drivers/ide/pci/pdc202xx_old.c:504 (Not tainted) Apr 2 17:00:14 dxr kernel: [<c025d255>] pdc202xx_reset_host+0x10c/0x14e [<c025d2a9>] pdc202xx_reset+0x12/0x2a Apr 2 17:00:14 dxr kernel: [<c02695d3>] do_reset1+0x10a/0x1d7 [<c02670c8>] ide_error+0x45/0x7e Apr 2 17:00:14 dxr kernel: [<c026cad0>] task_in_intr+0x63/0xdb [<c026ca6d>] task_in_intr+0x0/0xdb Apr 2 17:00:14 dxr kernel: [<c026815a>] ide_intr+0x10c/0x161 [<c013cd9d>] handle_IRQ_event+0x2e/0x5a Apr 2 17:00:14 dxr kernel: [<c013ce47>] __do_IRQ+0x7e/0xd7 [<c0104f3a>] do_IRQ+0x4a/0x82 Apr 2 17:00:14 dxr kernel: ======================= Apr 2 17:00:14 dxr kernel: [<c01038ba>] common_interrupt+0x1a/0x20 Apr 2 17:00:14 dxr kernel: Badness in pdc202xx_reset_host at drivers/ide/pci/pdc202xx_old.c:506 (Not tainted) Apr 2 17:00:14 dxr kernel: [<c025d292>] pdc202xx_reset_host+0x149/0x14e [<c025d2a9>] pdc202xx_reset+0x12/0x2a Apr 2 17:00:14 dxr kernel: [<c02695d3>] do_reset1+0x10a/0x1d7 [<c02670c8>] ide_error+0x45/0x7e Apr 2 17:00:14 dxr kernel: [<c026cad0>] task_in_intr+0x63/0xdb [<c026ca6d>] task_in_intr+0x0/0xdb Apr 2 17:00:14 dxr kernel: [<c026815a>] ide_intr+0x10c/0x161 [<c013cd9d>] handle_IRQ_event+0x2e/0x5a Apr 2 17:00:14 dxr kernel: [<c013ce47>] __do_IRQ+0x7e/0xd7 [<c0104f3a>] do_IRQ+0x4a/0x82 Apr 2 17:00:14 dxr kernel: ======================= Apr 2 17:00:14 dxr kernel: [<c01038ba>] common_interrupt+0x1a/0x20 Apr 2 17:00:14 dxr kernel: PDC202XX: Primary channel reset.
