Linux-1.99.6: "double lock on device queue!"

Some difficulties with Linux-pre2.0.6:

May 20 00:49:34 iguana kernel: double lock on device queue!
May 20 00:49:37 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:49:47 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:49:57 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:50:07 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:50:17 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:50:27 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:50:37 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:50:47 iguana kernel: Socket destroy delayed (r=0 w=268)
May 20 00:50:57 iguana kernel: Socket destroy delayed (r=0 w=268)

These come right after boot. I have seen those "Socket destroy
delayed" messages seldom so far. The message remains very same
also over reboot.

Machine is a i486DX50 w/ 20 MB RAM, IDE disk and SMC Ultra
ethernet card. It runs RedHat 2.1 distribution (libc-5.0.9,
gcc-2.7.0).

PS. Vger turnaround times have been improved very significantly
recently. Thanks to those people who have done that!
