Ok, with the SGI kdb in the kernel, I have the following information
available:

pid 266, httpd, in D state

kdb> btp 266
    EBP EIP Function(args)
0xcac21eec 0xc0114b92 schedule+0x25a( 0xc9c79d34, 0xc9c79ce0, 0xc9c79d50,
0xcac20000, 0x1234567)
0xcac21f34 0xc0109285 __down+0x129( 0xc9c79d34, 0xffffffff, 0xcac20000,
0xc01d9e1d, 0xca951b40)
0xcac21f94 0xc010951d __down_failed+08( 0xca951b40, 0x826b294, 0x5a,
0xca951b5c, 0xcac20000)
0xcac21fbc 0xc012dd54 sys_write+0xc4( 0x47, 0x826b294, 0x5a, 0x826b264,
0x826b294)
0xbffff7f4 0xc010ac7c system_call

after kdb> g, the kernel panicked and hard locked. fsck time...

another report will follow.
