Can you please work out where it hung? Enable the softlockup detector, nmi watchdog, try to get a sysrq-w or sysrq-t trace, etc?

Thanks.

New panic output is attached after adding softlockup. New found:
1, "strace mke2fs /dev/sdb1" works well. it just show many write(3, "\377\377...", 4096) =4096 .... 2, when system hang, ping this machine is workable. And keyboard input works but cmd has no output.

Can you please work out where it hung? Enable the softlockup detector, nmi watchdog, try to get a sysrq-w or sysrq-t trace, etc?

Thanks.

New panic output is attached after adding softlockup. New found:
1, "strace mke2fs /dev/sdb1" works well. it just show many write(3, "\377\377...", 4096) =4096 .... 2, when system hang, ping this machine is workable. And keyboard input works but cmd has no output.

This doesn't entirely implicate the aic79xx. The trace shows:

 <IRQ>  [<ffffffff803f99eb>] ? scsi_request_fn+0x31a/0x416

 [<ffffffff8020a198>] ? cpu_idle+0x45/0x63
 [<ffffffff804e4d50>] ? start_secondary+0x179/0x17d

So we locked up somehow in the mid-layer trying to feed a new command from the softirq. It would greatly help to know what line in scsi_lib.c

scsi_request_fn+0x31a/0x416

The trace implies SCSI is built in, so

addr2line -e vmlinux -f scsi_request_fn+0x31a

Should tell us (hoping you build with CONFIG_DEBUG_INFO).

Thanks Yi's help.
After enable CONFIG_DEBUG_INFO, this bug can not reproduce on 2.6.28-rc1. but it still exists on 28-rc2 kernel. Soft lockup catchs several times lockup. And they are same as the following one.

But seems gdb works for this.

In reply to James Bottomley

I did bisect for this bug and find the following commit cause this problem.

commit f0c0a376d0fcd4c5579ecf5e95f88387cba85211

Author: Mike Christie <[email protected]>

[SCSI] Add helper code so transport classes/driver can control queueing (v3)

SCSI-ml manages the queueing limits for the device and host, but does not do so at the target level. However something something similar can come in userful when a driver is transitioning a transport object to the the blocked state, becuase at that time we do not want to queue io and we do not want the queuecommand to be called again.
