Subject: stat of /proc fails after CPU hot-unplug with EOVERFLOW in 2.6.18
Date: Wed, 27 Sep 2006 09:55:47 +0200	[thread overview]
Message-ID: <451A2E83.5000806@cdi.cz> (raw)

Hello,

I have 2way Opteron machine. I've done this:
echo 0 > /sys/devices/system/cpu/cpu1/online

and then strace stat /proc:

[snip]
personality(PER_LINUX)                  = 4194304
getpid()                                = 14926
brk(0)                                  = 0x804b000
brk(0x804b1a0)                          = 0x804b1a0
brk(0x804c000)                          = 0x804c000
stat("/proc", 0xbf8e7490)               = -1 EOVERFLOW

When I do echo 1 > ... to start cpu again then the stat starts
to work again ... Weird.
