Hi, I'm seeing a kernel panic on a fairly recent 9.2-STABLE/amd-64 synced on 26 Dec 2013. It's easily reproducible on my system: 1. Call up squirrel-sql (running openjdk6) 2. Change the L&F to GTK+ 3. System panics. Thankfully, it's easily revertable! The relevant portions of core.txt: Unread portion of the kernel message buffer: panic: Bad entry start/end for new stack entry cpuid = 4 KDB: stack backtrace: #0 0xffffffff80949316 at kdb_backtrace+0x66 #1 0xffffffff8090ef1e at panic+0x1ce #2 0xffffffff80b83014 at vm_map_stack+0x274 #3 0xffffffff80b852bf at vm_mmap+0x67f #4 0xffffffff80b85a6c at sys_mmap+0x1dc #5 0xffffffff80cf368a at amd64_syscall+0x5ea #6 0xffffffff80cddda7 at Xfast_syscall+0xf7 I noticed in the archives that some other people are experiencing the similar kernel panics when using OpenJDK on 9.2-STABLE.
