PXE/NFS: Can SquashFS deal with temporary read-errors at all ?

I bootet ubuntu-10.04.1-desktop-i386.iso over NFS (as described in http://tinderblog.wordpress.com/2009/04/29/ubuntu-live-cdnetwork-boot/)
and found the diskless system serveral times hanging after a day or so with unrecoverable:

ubuntu kernel: [69366.882128] SQUASHFS error: squashfs_read_data failed to read block 0x28fecab6
ubuntu kernel: [69366.882135] SQUASHFS error: Unable to read metadata cache entry [28fecab6]
ubuntu kernel: [69366.882137] SQUASHFS error: Unable to read inode 0xf8c2c10ee

My Impression is that squashfs just can not handle temporary read-errors which may occur on NFS as as well as due to local IDE- or other HW-Iritations.

Having used diskless customized Knoppix - that survived server-reboots using compressed_fs instead of squashfs - I would like to migrate to Ubuntu but I doubt if i can do without repacking casper/filesystem.squashfs ...
