SunBlade150 TIMEOUT - READ_BIG retrying

[Andy Jam]

Hello FreeBSD SPARC-guys!

I've got a fresho distro of 6.1-BETA2 and tried to install it on my sunblade 150 but got the following console messages during a bin directory copying onto HDD:

54567936 bytes read from base dist, chunk 39 of 41 @ 718.0 KBytes/sec.       
acd0: TIMEOUT - READ_BIG retrying (1 retry left)

g_vfs_done():acd0[READ(offset=285249536, length=65536)]error = 5

How could it be fixed? Or maybe i should give a try to the most recent snapshot of CURRENT?
