** Description changed: Binary package hint: linux-image-2.6.17-10-generic I apologize for my very poor English. Any device is /dev/sdb goes slowly and when it works the system is unstable. hdparm -tT /dev/sda /dev/sdb returns /dev/sda: Timing cached reads: 1516 MB in 2.00 seconds = 756.88 MB/sec Timing buffered disk reads: 198 MB in 3.01 seconds = 65.70 MB/sec /dev/sdb: Timing cached reads: 1760 MB in 2.00 seconds = 878.71 MB/sec Timing buffered disk reads: 6 MB in 3.59 seconds = 1.67 MB/sec ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - Also whit new kernel 2.6.19 i have the some problem. + Also with new kernel 2.6.19 i have the some problem. Instead with kernel 2.6.15 (Dapper's kernel on Edge) it works properly: hdparm -t /dev/sdb /dev/sdb: Timing buffered disk reads: 178 MB in 3.00 seconds = 59.25 MB/sec It's a Ubuntu bug and not a kernel bug because with other distribution - linux whit kernel > 2.6.17 (as an example knoppix 5.10) it works. + linux with kernel > 2.6.17 (as an example knoppix 5.10) it works.
