Earlier today, I tried to unlock xscreensaver on my desktop. After typing in the password, it said "Checking..." and then hung. In response, I hit Ctrl+Alt+Bksp, which killed X. However, gdm did not restart X. I tried logging in on the console, but none of them were responsive; characters would echo, but nothing else.
In hopes of finding the problem, I entered kdb, and did a bta. All processes were hung in exactly the same spot, schedule+0x268! This code is as follows:
0xc0110d50 <schedule+252>: jne 0xc0110d7e <schedule+298> 0xc0110d52 <schedule+254>: test %eax,%eax 0xc0110d54 <schedule+256>: jne 0xc0110d72 <schedule+286> 0xc0110d56 <schedule+258>: mov 0xffffffe4(%ecx),%edx 0xc0110d59 <schedule+261>: test %edx,%edx 0xc0110d5b <schedule+263>: je 0xc0110d7e <schedule+298> 0xc0110d5d <schedule+265>: mov 0xfffffff0(%ecx),%eax 0xc0110d60 <schedule+268>: cmp 0xfffffff0(%ebp),%eax 0xc0110d63 <schedule+271>: je 0xc0110d69 <schedule+277> 0xc0110d65 <schedule+273>: test %eax,%eax 0xc0110d67 <schedule+275>: jne 0xc0110d6a <schedule+278> 0xc0110d69 <schedule+277>: inc %edx 0xc0110d6a <schedule+278>: add $0x14,%edx 0xc0110d6d <schedule+281>: sub 0x24(%esi),%edx 0xc0110d70 <schedule+284>: jmp 0xc0110d7e <schedule+298>
Additionally, I did a "ps" in kdb and found dozens of "cron" and "sh" started. I suspect that these processes were somehow related to the lockup, as the machine should've been idle for hours, and no cron jobs were scheduled for the time.
The captured "bta" is availible if anyone is interested. I don't know of a way to reproduce this offhand. -- -Steven Freedom is the freedom to say that two plus two equals four. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
