Since I updated from 2.6.27 to 2.6.27-git10 it doesn't find its root fs in 2 out of 3 boots. The r8169 gets detected, but there is never a message that it finds the link in the failed cases: r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded r8169 0000:02:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 r8169 0000:02:00.0: setting latency timer to 64 r8169 0000:02:00.0: irq 45 for MSI/MSI-X eth0: RTL8168b/8111b at 0xffffc2000035a000, 00:00:00:00:00:00, XID 38000000 IRQ 45 I tried to revert back to the 2.6.27 r8169.c and that fixed the problem here. Didn't see a hang so far in 4 boots with the old driver. I also originally thought it was related to netconsole, but even with that removed the problem still happens. -Andi -- ak@linux.intel.com
