Two issues so far. DUMMY(mount) needs to be added to sys/alpha/linux/linux_dummy.c to make the module load. The second, much more serious problem, is that when I run the Compaq JRE/JDK for linux the system locks up. It responds to pings,etc. But all shells are dead, X locks up, etc. Its like its in a really tight loop in sigsuspend().. This is reproducible. The stack trace looks like this: db> tr siointr1() at siointr1+0x160 siointr() at siointr+0x14 isa_handle_intr() at isa_handle_intr+0x2c alpha_dispatch_intr() at alpha_dispatch_intr+0x8c interrupt() at interrupt+0x1d8 XentInt() at XentInt+0x28 --- interrupt (from ipl 0) --- tsleep() at tsleep+0x394 sigsuspend() at sigsuspend+0xd8 osf1_sigsuspend() at osf1_sigsuspend+0x84 syscall() at syscall+0x224 XentSys() at XentSys+0x5c --- syscall (111, Linux ELF, osf1_sigsuspend) --- --- user mode --- db> Yes, I realize that's an osf1_sigsuspend() getting called through the linux sysent. It works fine in the old, pre-patch code. I don't understand how you could have broken this with your patch. Any ideas?
