[uml-devel] 2.6.0 uptime bug

[uml-devel] 2.6.0 uptime bug

[Patrick Kilian]

Hi,

I found a bug in the 2.6.0-test? kernels. /proc/uptime shows a uptime 
since the start of the epoch, approx. 33 years.
Is anybody able to reproduce this bug?

mfg,

is to write a pr0n server that serves thumbnails over IPv[46]
and full-size images over IPv6 only.              -- Ingvar

Have you been able to figure out whether this is also a problem for other
ports?  Your patch suggests that it is, and if it is, then you should send
it to LKML so it can be fixed in mainline.

I don't know if other arch beside uml give the wrong uptime. If anyone could 
check this on i386 or other "read" hardware I'd be glad to hear the result. 
Looking at the code and the callpath all arch should have this bug. If 
someone is able to confirm this I'm going to post the patch to the lkml.
