Hi, I'm having problems booting from a SATA disk with 2.6.19. Grub loads fine, but when the kernel boots, it *sometimes* ends up with VFS: Cannot open root device "sda5" or unknown-block(0,0). This issue appears to be identical with the one reported in http://lkml.org/lkml/2006/10/19/327 except that 2.6.19 did not fix it for me. In fact, it made it worse. The timeouts reported in that thread are still present and with 2.6.19 the fraction of unsuccessful boots has increased from 30% to 80%. I often have to reboot my machine 3 times in a row before it succeeds. I have tried both vanilla 2.6.19 and gentoo-sources-2.6.19-r1 To summarize: My machine stalls for nearly a minute on all boots and the root filesystem fails to mount on 80% of the boots. This problem first manifested itself when I switched to 2.6.18 and has become worse with 2.6.19. The controller: 00:1f.2 IDE interface: Intel Corporation 82801FB/FW (ICH6/ICH6W) SATA Controller (rev 03) I don't know how to get the logs from an unsuccessful boot.
