Can you please post the oops? Have you done so already? What makes you think it is the same race discussed in the above thread? BTW, I fail to see any drivers/char/pty.c change related to the race which triggers the pty_chars_in_buffer-0 oops. Quoting the first message from thread you mention: That last call trace entry is the call in pty_chars_in_buffer() to /* The ldisc must report 0 if no characters available to be read */ count = to-ldisc.chars_in_buffer(to); Alan, Linus, what correction to the which the above thread discusses has been deployed? Provided in thread patch from Linus working, but after night i have checked server, and see load average jumped to 700. Can anybody help in that? I am not kernel guru to provide a patch, but seems by search
pty_chars_in_buffer NULL pointer (kernel oops)

I am not kernel guru to provide a patch, but seems by search in google it is actual problem for people, who own poptop vpn servers, it is really causing serious instability for servers. -- With best regards, GlobalProof Globax Division Manager, Denys Fedoryshchenko mailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
