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.
Martin
