[uml-devel] Long time no talk, 2.4.18-um2 oddness.

[Mooneer S. <mo...@ea...>]

Hello,

Long time no talk :) When using 2.4.18-um2 and the Debian 2.2 root FS, it
panics when it's time to load Apache-SSL:

Starting portmap daemon: portmap.
Starting NFS common utilities: statd.
Starting internet superserver: inetd.
Not starting NFS kernel daemon: No exports.
Starting mail transport agent: Postfix.
Starting OpenBSD Secure Shell server: sshd.
Starting professional ftp daemon: proftpd.
Starting web server: apache.
/usr/sbin/apachectl start: httpd started
Starting web server: apache-ssl.
Reading key for server usermode.translator.cx:443
Launching... /usr/lib/apache-ssl/gcache
pid=206
Kernel panic: Kernel mode fault at addr 0x28, ip 0xa00c901f

Running strace on UML after the panic produces:

gettimeofday({1015647694, 44547}, NULL) = 0
ptrace(PTRACE_PEEKUSER, 11314, 4*EIP, [0xa000d230]) = 0
ptrace(PTRACE_CONT, 11314, 0, SIGVTALRM) = 0
wait4(-1, [WIFSTOPPED(s) && WSTOPSIG(s) == SIGVTALRM], WUNTRACED, NULL) = 11314
--- SIGCHLD (Child exited) ---
gettimeofday({1015647694, 94549}, NULL) = 0
ptrace(PTRACE_PEEKUSER, 11314, 4*EIP, [0xa000d232]) = 0
ptrace(PTRACE_CONT, 11314, 0, SIGVTALRM) = 0
wait4(-1, [WIFSTOPPED(s) && WSTOPSIG(s) == SIGVTALRM], WUNTRACED, NULL) = 11314
--- SIGCHLD (Child exited) ---
gettimeofday({1015647694, 144553}, NULL) = 0
ptrace(PTRACE_PEEKUSER, 11314, 4*EIP, [0xa000d230]) = 0
ptrace(PTRACE_CONT, 11314, 0, SIGVTALRM) = 0
wait4(-1, [WIFSTOPPED(s) && WSTOPSIG(s) == SIGVTALRM], WUNTRACED, NULL) = 11314
--- SIGCHLD (Child exited) ---
gettimeofday({1015647694, 194554}, NULL) = 0
ptrace(PTRACE_PEEKUSER, 11314, 4*EIP, [0xa000d230]) = 0
ptrace(PTRACE_CONT, 11314, 0, SIGVTALRM) = 0
wait4(-1, [WIFSTOPPED(s) && WSTOPSIG(s) == SIGVTALRM], WUNTRACED, NULL) = 11314

(goes on and on and on in what seems to be an infinite loop)

I wonder if it's a reaction with gcache or if it's because I'm still 
running stable in UML.
(I'm also using hostfs as the root filesystem, if that matters). Host box 
is running RedHat
6.2, with 2.4.18 kernel and the 2.4.18-um2 RPM.

Thanks,
