| |
Hello,
it appears that the same NFS-related soft-lockup is still in 2.3.6pre1. I can trigger it now using the command
find . -type f -print|xargs -n 1000 md5sum
inside an NFS-mounted directory. Precondition is the mount option rsize=4096,wsize=4096, I cannot trigger the bug using rsize=1024,wsize=1024.
I managed to capture some EIP values:
c01d600e stext_lock+0x22D2 c01d6007 stext_lock+0x22CB c010ae07 __global_cli+0xCB c01d2391 __delay+0x21 c01d2390 __delay+0x20 c01d2380 __delay+0x10 c01d2370 __delay c01d23a6 __udelay+0x12
After some time hitting Sysreq-P I got the message:
wait_on_irq, CPU 1 irq: 0 [0 0] bh: 1 [1 0] <[c010adfd]> <[c011615c]> <[c01538e5]> <[c0128f21]> <[c0109168]>
This translates to: c010adfd __global_cli+0xC1 c011615c do_syslog+0x2DC c01538e5 kmsg_read+0x11 c0128f21 sys_read+0xC5 c0109168 system_call+0x34
The system is based on Dual-PentiumII, 233MHz, Gigabyte GA-686LX2 motherboard. The kernel is compiled with egcs 1.1.2.
The remote NFS-server is Linux-2.2.7, Universal NFS Server 2.2beta29.
