I/O read failure

[Alex Povolotsky]

Hello!

I understand (in general), what does the following mean:

Oct  9 12:01:36 techno /kernel: (da2:ahc0:0:2:0): Invalidating pack
Oct  9 12:01:36 techno /kernel: spec_getpages:(#da/0x20014) I/O read failure: (error=6) bp 0xcfeb8f3c vp 0xe0677840
Oct  9 12:01:36 techno /kernel: size: 5632, resid: 5632, a_count: 5274, valid: 0x0
Oct  9 12:01:36 techno /kernel: nread: 0, reqpage: 0, pindex: 0, pcount: 2
Oct  9 12:01:36 techno /kernel: vm_fault: pager read error, pid 41049 (httpd)
Oct  9 12:01:36 techno /kernel: spec_getpages:(#da/0x20014) I/O read failure: (error=6) bp 0xcfeb61d8 vp 0xe0677840

but can I extract more useful information from numbers?
