Hi, i uploaded a blkparse to my bugreport.
I don't get it, in addition to not knowing why the freeze happens, now
i even don't know why it does NOT freeze.
:-(

(libata.atapi_passthru16=0 was set, shout it have been '1Ah'
ATA_PASS-THROUGH(12) instead? and why no freeze??)

(i hope... should i?, ?? A1h is both IDENTIFY_PACKET_DEVICE
and ATA PASS-THROUGH(12) ?? )
#15: 00, CONTROL
I also performed the test on System #2 (without
'libata.atapi_passthru16=0' tand the blkparse output looks similar:
11,0 1 86 27.195169571 10620 I R 512 (85 08 2e 00 00
00 01 00 00 00 00 00 00 00 a1 00 ..) [ata_id]

00 01 00 00 00 00 00 00 00 a1 00 ..) [ata_id]
[...TRUNCATED...]
11,0 1 88 27.196006926 10613 C R (85 08 2e 00 00 00 01
00 00 00 00 00 00 00 a1 00 ..) [2]
With the execption of the "[2]" instedd of "[0]". And there was no
logged error on System #2.
Cheers.
