[CentOS] latest kernel

Sat Sep 2 19:37:28 UTC 2006

Marko

I have 5 servers running CentOS.

Four of them work fine with the 42 kernel.

The fifth I use as a yum respository and when I try to use the 42 kernel I
lose all network connectivity.

Reverting to the earlier kernel on this box restores connectivity.

I append some dmesg excerpts which suggest that the new kernel handles PCI
(GSI) differently, but have not had the time to investigate further.

Please let me know if you find a solution.

Best wishes

Clive
