Today I decided to update my old el5
kernel with yum after years. What I didn't know is that the kernel that was running was custom and after updating and rebooting the network drivers started to fail loading and so I decided that booting from an older kernel would spare me more time than trying to fix the custom one.
The previous, custom kernel was 2.6.39
and the current, downgraded one is 2.6.18-308.11.1
(both x64
).
The network drivers are loading correctly again after the downgrade, but now ping
is not measuring in the microseconds range anymore. Instead, it'll only round up/down to the nearest milisecond integer, like this:
PING 10.10.10.1 (10.10.10.1) 56(84) bytes of data.
64 bytes from 10.10.10.1: icmp_seq=1 ttl=64 time=1.00 ms
64 bytes from 10.10.10.1: icmp_seq=2 ttl=64 time=0.000 ms
64 bytes from 10.10.10.1: icmp_seq=3 ttl=64 time=2.00 ms
64 bytes from 10.10.10.1: icmp_seq=4 ttl=64 time=1.00 ms
64 bytes from 10.10.10.1: icmp_seq=5 ttl=64 time=0.000 ms
Is there any known settings in the kernel that makes this happen? I searched a bit on Google but didn't find a single individual with the same problem.
