hello all, i have os2008.11 on dell precision m70 laptop. After having important slowness on disk, i change menu.lst in grub to remove: ata-disk-dma-enabled=0 on kernel line. It works better, but after suspend-resume, i'm unable to have access to my session, and cannot ssh into the laptop, the disk led is continuously red, so i wonder if i am concerned by the bug 4429794 ATA: sys w/ AWARD BIOS, IBM ultra-DMA disk hangs after soft reboot http://bugs.opensolaris.org/view_bug.do;jsessionid=9eaac2c1525aa2dfa5f802b4b2d1?bug_id=4429794
before the remove, there were: Dec 12 09:19:19 delljm genunix: [ID 846691 kern.info] model WDC WD400VE-75HDT1 Dec 12 09:19:19 delljm genunix: [ID 479077 kern.info] ATA/ATAPI-6 supported, majver 0x7e minver 0x0 Dec 12 09:19:19 delljm genunix: [ID 228648 kern.info] ata_set_feature: (0x66,0x0) failed Dec 12 09:19:19 delljm npe: [ID 236367 kern.info] PCI Express-device: ide at 0, ata0 Dec 12 09:19:19 delljm genunix: [ID 936769 kern.info] ata0 is /pci at 0,0/pci-ide at 1f,2/ide at 0 Dec 12 09:19:19 delljm genunix: [ID 935449 kern.info] ATA DMA off: disabled by "ata-disk-dma-enabled" property Dec 12 09:19:19 delljm genunix: [ID 882269 kern.info] PIO mode 4 selected Dec 12 09:19:19 delljm gda: [ID 243001 kern.info] Disk0: <Vendor 'Gen-ATA ' Product 'WDC WD400VE-75HD'> and after the remove: Dec 15 08:02:46 delljm genunix: [ID 640982 kern.info] IDE device at targ 0, lun 0 lastlun 0x0 Dec 15 08:02:46 delljm genunix: [ID 846691 kern.info] model WDC WD400VE-75HDT1 Dec 15 08:02:46 delljm genunix: [ID 479077 kern.info] ATA/ATAPI-6 supported, majver 0x7e minver 0x0 Dec 15 08:02:46 delljm genunix: [ID 228648 kern.info] ata_set_feature: (0x66,0x0) failed Dec 15 08:02:46 delljm npe: [ID 236367 kern.info] PCI Express-device: ide at 0, ata0 Dec 15 08:02:46 delljm genunix: [ID 936769 kern.info] ata0 is /pci at 0,0/pci-ide at 1f,2/ide at 0 Dec 15 08:02:46 delljm genunix: [ID 773945 kern.info] UltraDMA mode 5 selected Dec 15 08:02:46 delljm gda: [ID 243001 kern.info] Disk0: <Vendor 'Gen-ATA ' Product 'WDC WD400VE-75HD'> thanks in advance for help, gerard
